I've tried to follow https://developer.android.com/google/play-services/setup.html instructions in Eclipse for Mobile Developers (Juno), but am getting multiple errors with the library package after importing the library project into my workspace. I fixed the AndroidManifest.xml error it reported, but now I can't open the project in Eclipse saying the .project description file contains invalid information. So much for a simple install. I've tried uninstalling it, redownloading it, and I still get the multiple errors. Any suggesions how to get it working?
There is a misleading step in step 3 of http://developer.android.com/google/play-services/setup.html:
Copy the
/extras/google/google_play_services/libproject/google-play-services_lib
library project into the source tree where you maintain your Android
app projects.
If you are using Eclipse, import the library project into your
workspace. Click File > Import, select Android > Existing Android Code
into Workspace, and browse to the copy of the library project to
import it.
Don't do the first copy. Instead just do the second part and check the box that says "Copy projects into workspace". I found that if I did the first part I would end up with empty xml files.
Try the following :
https://developers.google.com/maps/documentation/android/intro#sample_code
You would get errors while opening an activity mentioned in the sample code. That is because android.support.v4.app.FragmentActivity is not added to your build path. Hover over the error and click on "Fix Project Setup". It would ask you to add the lib to the build path. Say Yes and enjoy :)
If your google_pay_services/libproject is empty (mine was empty) and looks like installed in sdk manager, first delete google play services from sdk manager, install it again and follow the steps in the first answer.
Try Window > Android SDK Manager > Extras > Google play service > Delete package.
And then re-install that package again:
File > Import, select Android > Existing Android Code into Workspace
I had the same problem. I went to Properties->Java Build Path and clicked on the Projects tab. Then I added google-play-services_lib using the Add button. This got me this run-time exception:
E/AndroidRuntime(9469): Caused by: java.lang.ClassCastException: com.google.android.gms.maps.MapFragment cannot be cast to android.support.v4.app.Fragment
So then I changed the main.xml file entry from this:
android:name="com.google.android.gms.maps.MapFragment"
to this:
android:name="com.google.android.gms.maps.SupportMapFragment"
And FINALLY, it runs, but NOW no map due to authorization failure. So I am off on another search.
thanks Google for making it so complicated and for posting incorrect instructions!

I had made an maven project and it worked fine.
Then I installed plugins
EclEmma Java Code Coverage,
PHP Development Tools (PDT),
Eclipse.orgSonarQube
Then I worked on some other project. When I again wanted to create an maven project,it threw the following error window which said
The selected wizard could not be started
reason
plug-in org.eclipse.m2e.core.ui was unable to load class
org.eclipse.m2e.core.ui.internal wizards.MavenProjectWizard
Removed SonarQube plugin .This solved the issue.
Now it works all fine.
But is there any other solution to this problem since I have to use sonar.
Click on eclipse help tab and open installation details search sonar and remove all related plugins.
That's not quite the right characterization of what it says on the page,Please check your .log file /path/workspace/.metadata/
Find the correct plugin which is causing this problem and update to compatible version of the plugin with eclipse version.
To find the hidden files in the workspace use Ctrl+H
I had the same problem, and I've tried so many solutions. But what I did to solve the problem, is that I just upgraded my Eclipse IDE (2019-06 to 2020-03) by following these steps (from https://wiki.eclipse.org/FAQ_How_do_I_upgrade_Eclipse_IDE%3F) :
You first need to add the new release's repository as follows:
1-1. Window > Preferences > Install/Update > Available Software Sites
1-2. Click 'Add'
1-3. Enter the URL https://download.eclipse.org/releases/2020-03/
1-4. Click 'Ok'
Help > Check for Updates
If updates are found, proceed through the install wizard and restart the IDE when
prompted. Otherwise, read carefully the error message to find out which component
is conflicting and establish your resolution strategy.
Note that the start splash screen may be cached and will not necessarily be
updated to the latest version after the IDE is restarted. Performing a full
relaunch should display the new version number.
Okay I am starting to give up with this. I have been trying to setup sebversion in Eclipse for my android project. I have been following the following tutorial
http://blog.bauson.com/eclipse-subclipse-svn-hostgator-com.html
I got the following:
Created a repository called myRep
Created a project under with source files myRep/TestProject and attached it to trunk
installed subclipse and got it to grab the repository
Now when, it says "Checkout as a project configured using the new project wizard", I get to choose the type of project. If I choose android application project then it creates a default android project and nothing is checked out. But when I choose General Project, it does grab the whole thing in the following structure
Repositony->TestProject->Trunk->All my android files and folders
However I want it to be android project so I can compile and run it. I did a lot of googling and I need your help pleeease!
Never mind, I figured it out. Apperently, when you choose the repository you have to right click and click refresh and it will show you a list of Folders (stupid eclipse does not do it automatically). Then you choose your project and create it as a new project. Voilla, you get it compiling and running
What is the straight-forward way of importing one of the GWT samples in eclipse Helios + GWT 2.1.1. It seems like the content of the zip file doesn't contain any project files for eclipse.
I tried the following:
create a GWT project 'bla'
Delete the src ad war folder and
replace it with the src and war
folder from the sample
refresh the project in eclipse
hit 'run'
[ERROR] Unable to find
'bla/bla.gwt.xml' on
your classpath; could be a typo, or
maybe you forgot to include a
classpath entry for source?
So I go to the run configuration and remove the path for the example projects from the arguments list. I also changed the name of hosted html page to the one in the sample. Hit 'run' and:
[ERROR] Invalid version number "2.0"
passed to external.gwtOnLoad(),
expected "2.1"; your hosted mode
bootstrap file may be out of date;
Now I need an out of date version of GWT to run these samples? What is going on, I just want to look at a sample to learn a new concept.
Reading the readme.txt in the GWT samples directory I came across a solution that works on Eclipse 3.7. Assuming you have ant installed on your machine, execute the following from the sample's directory:
ant eclipse.generate
This will generate both the .classpath and .project files needed to import the sample into Eclipse and run it.
Here the relevant excerpt from README.txt:
-- Option A: Import your project into Eclipse (recommended) --
If you use Eclipse, you can simply import the generated project into
Eclipse. We've tested against Eclipse 3.4 and 3.5. Later versions
will likely also work, earlier versions may not.
If the directory containing this file does not have a .classpath or
.project file, generate them by running 'ant eclipse.generate'
In Eclipse, go to the File menu and choose:
File -> Import... -> Existing Projects into Workspace
Browse to the directory containing this file, select "Mail".
Be sure to uncheck "Copy projects into workspace" if it is checked.
Click Finish. You can now browse the project in Eclipse.
To launch your web app in GWT development mode, go to the Run menu and
choose:
Run -> Open Debug Dialog...
Under Java Application, you should find a launch configuration
named "Mail". Select and click "Debug".
You can now use the built-in debugger to debug your web app in
development mode.
In eclipse 3.7, instead of Run -> Open Debug Dialog..., its Run -> Debug Configurations. I got both the showcase and mail samples running following those commands. Should work for all of the other samples as well.
The examples that come with GWT SDK were built in different ways. Some are Maven builds, others use Ant. Eclipse can handle these common builds directly, but you have to choose the right option.
So, if you want to open the Expenses project in eclipse, you would look in the projects root directory (i.e. ../gwt2.4/samples/Expenses) where you'll find a file called pom.xml. That is a Maven build file. To import it into your Work space select:
File->Import...
Open Maven->Existing Maven Projects, and click on Next > button
Browse your file system til you reach the Expenses folder. Click on it and Select OK.
At this point it will show you the Projects in that directory in the Projects: area of the window...only one in this case: /pom.xml com.google.gwt.sample.expenses:...etc.
click on the checkbox for that project, Next>
Finally, it ask you to map plugins. You'll need to select in the drop down menu under Actions the required plugins (such as m2e).
In other project folders you may find a build.xml file instead. That's an Ant build file. To import that you do something similar, but different (of course!):
File->New->Project...
Open the Java folder and select "Java Project from Existing Ant Buildfile", Next >
Click the Browse button, dig through your directory to the project folder and select the build.xml file, and Open it.
Project name should fill in automatically, just select the declaration to use in the middle window and click Finish.
Since those tutorial only include the src and war directory, the idea remains to:
create a new project following this tutorial
remove any created class part of the example files which are automatically added (see Issue 1547)
Unfortunately the Google Plugin does not allow to created a new Web Application Project without creating template files. The template files are nice for the first try but annoying if you want to start from scratch with a new GWT application.
copy the src and war directory in place within the now empty project
Following your ticket 5847 (No easy and straight-forward way to make examples work in eclipse),
as xo4yhamope comments, you need the right GWT option.
and did you consider the Issue 5038 about the error message:
Unable to find 'xxxx.gwt.xml' on your classpath;
could be a typo, or maybe you forgot to include a classpath entry for source?
This message usually means you attempted to refresh the browser before dev mode has had a chance to finish loading the module.
The uppercase/lowercase confusion happens because the module has been renamed to 'stockwatcher', but dev mode cannot map 'stockwatcher' to "StockWatcher' until it has finished loading the entire module.
So, it's just a matter of waiting a few seconds longer after the Development Mode pane says I should go to http://127.0.0.1:8888/StockWatcher.html?gwt.codesvr=127.0.0.1:9997 ?
That seems a little messed up. It should wait until it's actually ready before telling me it's ok, because users (like me) are going to go there as soon as the UI says it's ready.
The other confusing part is that the server begins serving the host page as soon as that message in the UI comes up. Because this was happening, I assumed that the server was completely up, even though (as it turns out) it wasn't.
Anyway, waiting a few more seconds seems to resolve the "Unable to find 'stockwatcher.gwt.xml' on your classpath" problem. Thanks!
I'm beginning to suspect this is a bug in the samples. I am adding this answer so it can be marked as an answer when I get confirmation about that.
I was trying out some other samples and came across this page. At the top is a little explanation for how to download and import the sample.
Before you begin
The StockWatcher project
This tutorial builds on the GWT
concepts and the StockWatcher
application created in the Build a
Sample GWT Application tutorial.
If you have not completed the Build a
Sample GWT Application tutorial and
are familiar with basic GWT concepts,
you can import the StockWatcher
project as coded to this point.
Download the StockWatcher project.
Unzip the file.
Import the project into Eclipse
From the File menu, select the Import... menu option.
Select the import source General > Existing Projects into
Workspace. Click the Next button.
For the root directory, browse to and select the StockWatcher
directory (from the unzipped file).
Click the Finish button.
If you are using ant, edit the
gwt.sdk property in
StockWatcher/build.xml to point to
where you unzipped GWT.
Now this is what I call straight-forward and easy.
At that point I had already built the StockWatcher in a previous tutorial but I got intrigued by the fact that it was explained exactly as I tried it the first time. So I downloaded the project and it had the correct eclipse project structure. I tried to import it 'et voila' I have the project in eclipse. I runs out of the box (with warnings). That is how expected the samples to be.
This experience leads me into thinking that the sample projects are malformed (as eclipse projects) and need to be updated. Let's hope my issue report leads to results.
-- Option A: Import your project into Eclipse (recommended) --
If you use Eclipse, you can simply import the generated project into Eclipse.
We've tested against Eclipse 3.4 and 3.5. Later versions will likely also
work, earlier versions may not.
If the directory containing this file does not have a .classpath or .project
file, generate them by running 'ant eclipse.generate'
In Eclipse, go to the File menu and choose:
File -> Import... -> Existing Projects into Workspace
Browse to the directory containing this file,
select "Mail".
Be sure to uncheck "Copy projects into workspace" if it is checked.
Click Finish.
You can now browse the project in Eclipse.
Copy from readme.txt supplied by samples. I tried this method, it's OK.
To import GWT showcase(2.5.1) I did following steps:
Create a new Google Web Application Project
New –> Other –> Google –> Web Application Project
Provide the project name “Showcase” and the Package name is com.google.gwt.sample.showcase
Click Finish
Go to eclipse plugin folder and traverse to the gwt
Under that folder go to gwt-2.3.\samples\Showcase
Copy (Ctrl C) all the contents. The contents are
a. src
b. test
c. war
d. build.xml
e. README.txt
In the eclipse, right click on the Showcase project and paste. Overwrite all the files
The files should start copying without any problem
Right click on the Showcase and Run As “Web Application”
You should have your Showcase working like Gem!
For me it worked like a charm ;)
Ref : http://simplestepswebdev.wordpress.com/2011/05/16/import-gwt-samples-into-eclipse/
I have imported a project with Mercurial (hg clone ...).
When opening it with Eclipse, a red exclamation mark appears by the project's name in the Project Explorer, and it cannot be built. Silly messages like "import java.util cannot be resolved" appear, and errors in files are not marked in the Package Explorer.
How can I resolve this?
Check the problem view. By exclamation it is usually means a problem with build path
Check the Build Path of the project by right clicking the project and select Build Path -> Configure Build Path.
One problem I often encountered is different people using different Java SDK and so when the exact SDK is not available in your machine, you need to change to your Java SDK (via JRE System Library -> Alternate JRE). A better way to avoid this problem is to always select the JRE System Library from Workspace default JRE or Execution Environment.
I solved the problem by adding the external .jar file in to my project.
RightClick on the project -> Properties -> Java Build path -> libraries tab -> Add jar
Select your jar file and added it
Thats it the red ! mark gone.
Some times it happens that you have added a jar file earlier but currently not using it. Then after some time you delete the jar file from your system. But since you are not using the library file, so you will not get any error.But then you will see the red exclamation mark for the project. So all you need is to remove the added jar from the Build Path.
Done.....
The Java Runtime Library was defined wrong for the pulled project.
It had to be reset under Project | Properties | Java Build Path | Libraries.
It means there is a problem with the build path in your project. If it is an android project then it mostly means the target value specified in project.properties file cannot be found. This can also be caused because of other kinds of built problems. But it is shown mostly for built problems only. See here for more details. It is about built error decorater seen in eclipse.
An extract from that page:
Build path problems are sometimes easy to miss among other problems in a project. The Package Explorer and Project Explorer views now show a new decorator on Java projects and working sets that contain build path errors:
The concrete errors can be seen in the Problems view, and if you open the view menu and select Group By > Java Problem Type, they all show up in the Build Path category:
I figured out each time i am trying to import a library into my android project, i have a red exclamation mark with both ActionBarSherlock and Facebook libraries
This is how i solved it:
After adding the library into your project "project properties->Android->Librairy->add"
If you are using Eclipse, all you have to do is to clean your project and build all your workspace:
"project -> clean... -> "clean selected project" -> build the entire workspace
For me, the problem was a simple one - the reference project was compiled in 1.5 and my project 1.6. Matching the two solved the issue.
Right-hand-click on the project, select properties, select java compiler.
This is how I solved this problem:- Right-Click to project->properties->Java Build Path->Libraries(tab)->Remove the Jar which is already present there with a Path given along.
I am trying to following instructions to import android java source to
eclipse on mac:
http://source.android.com/source/using-eclipse.html
I did create a new partition ('Mac OS Extended, case sensitive, journaled) on Mac.
I was able to build android sdk successfully at command line.
But when I try to create a new eclipse project and I get this error
which prevents eclipse from building the android source:
The project was not built due to "A resource exists with a different
case: '/android/out/target/common/obj/JAVA_LIBRARIES/
android_stubs_current_intermediates/classes/MANIFEST.mf'.".
Fix the problem, then try refreshing this project and building it since it may
be inconsistent android
Can you please tell me how can to fix my problem?
I just ran into this issue. It occurs when you have a case mismatch on package names. I resolved it by closing Eclipse and reconciling all package names in my project folder (under bin, gen and src) as well as in my AndroidManifest.xml. Once everything matched, I reopened Eclipse, did a Clean and Build and the error went away.
I encountered this problem when I had 2 seperate packages with different case defined in same project
src/main -> com.mycompany.project.DAO
src/test > com.mycompany.project.dao
Actually the 2nd package was for JUnit test cases & should not have been on build path. When I removed the 2nd package from build path (rightclick src/test -> remove from build path), this error was gone.
Just check your Manifest file. The package name/path should be correct. Then just delete R.java file, and clean the project. If dat doesnt solve the problem, close eclipse, and start again.
I faced same issue on windows.
Right click on your project, select Build Path -> Configure Build Path. Under "Source Project" tab check the case of the word "BIN". if BIN is in caps then make it the same as it is in your project tree hierarchy.
It is because of your jar file.
remove the jar and add correct jar.
Just solve the same problem.
Clean project and Delete R file.
Restart eclipse, then check "Problems" tab
I found two R file is mismatch, correct it and problem solved!
For me what worked was "switch workspace" to a new one.
(because the old one was contaminated
)
I had the same issue when importing an existing project into Eclipse. I named the new project package com.example.myproject but the old activity was referencing package com.example.MyProject (notice the uppercasing difference). After I renamed the package the project built fine.
1_ match "package" parameter in the manifest XML tag exactly with the package name in Src Java files.
com.example.myapp is not com.example.MyApp
2_ delete all things in Gen folder
3_ Project -> Clean
enjoy :)
Tried many of the above resolutions myself. I found it was better to just remove the application from my workspace and re-Import it. Resolved itself after that.
Old question, but this happened to me recently. I renamed the project in eclipse from ABC to Abc. I found the problem in the hidden ".project" file ... It still had the uppercase variant "ABC". I change the case in the .project file to Abc ... And all is well.
