I have created a Ceylon project in Eclipse Oxygen.
There are Ceylon source code files in the folder C:\Users\Jon\Aukitekt\milling\source\designs, but these are not shown inside Eclipse, as can be seen in this screenshot:
EDIT:
Making a single run, to 'kickstart' Eclipse, seems not possible. In run configuration I cannot click 'Run', for some reason.
Refreshing the Project Structure Window (right click -> refresh) revealed two files in the root:
ceylonb
ceylonb.bat
but no files in the source directory was revealed.
The problem might boil down to Eclipse not recognizing this as a proper Ceylon project, as suggested by Vitaly Banchenko.
The problem was that the project was not created as a proper Ceylon project.
When creating the project, choose
File -> New -> Ceylon project
rather than
File -> New -> Project

After creating the Maven Project in Eclipse from maven-archetype-webapp archetype i have the src/main/java not seen in project explorer and advices from same topic here do not work, so it is not a duplicate, because:
in my effective POM already stays :
<sourceDirectory>X:\Programming\workspaceEclipse\TomkatFromArchetype\src\main\java</sourceDirectory>
<scriptSourceDirectory>X:\Programming\workspaceEclipse\TomkatFromArchetype\src\main\scripts</scriptSourceDirectory>
<testSourceDirectory>X:\Programming\workspaceEclipse\TomkatFromArchetype\src\test\java</testSourceDirectory>
<outputDirectory>X:\Programming\workspaceEclipse\TomkatFromArchetype\target\classes</outputDirectory>
<testOutputDirectory>X:\Programming\workspaceEclipse\TomkatFromArchetype\target\test-classes</testOutputDirectory>
what is actualy ok.
But after updating maven, installing, building - whatever, i can not get the damn src/main/java shown in the project explorer and can create new java classes only in src/main/ressources.
I want generally know what is the reason for that behaviour, options for folders in m2E, so i could turn it and configure in different ways manually.
Some more info:
The folder src/main/java is sort of "exist", because if i try to create the folder, it shows that there is one with this name, but is not seen.
Opening project properties (right click) -> java build path ,stays
src/main/java and src/test/java (missing), how can it be?
Solved by looking in the file explorer, is the path realy there.
If it is there,it may be added in project explorer menu. If not - you create it in file explorer and add in project explorer menu
this issue occur into eclipse many time. you need to go to Project property > project facets and click on convert to faceted from.. then apply and ok. after this you can see the src/java/main into your project resources. you can fine image below:
One solution that could work in this scenario(suddenly src main java folder vanishes) is :
delete the project from the workspace. (not from disk)
re-import the project again as Maven project.
This worked in my case.
I am using Eclipse Juno SR1 Java EE, and checked out code from SVN as an Eclipse project. I am able to click on files in the project to verify everything was ok. The next time I rebooted, I can't see the project in the Project Explorer window.
A few things I checked: The menu item Project > Open Project is greyed out, indicating there are no closed projects. The project's file tree exists in my workspace. Eclipse won't let me create a new project with the same name because one already exists.
This is my first time using Juno, is there some new control that hides projects from view?
"File -> Import -> General -> Existing Projects Into Workspace"
"File -> Import -> Android -> Existing Android Code Into Workspace" doesn't do what you're trying to accomplish (been there...).
Assuming the above lines mean what they say, the first tells Eclipse to recognize what you're importing as an official Project. The 2nd tells Eclipse that you're importing only the code, not the Project itself.
Sometimes it's just because .project file is missing. If you have any other project, copy its .project file and paste inside the main folder of the project you're trying to import.
Try starting with the clean option in command line, maybe that should fix it
eclipse -clean
try
file -> switch workspace -> other
and tell eclipse where your workspace is
I was facing the same problem with RAD. What I did was:
imported only those projects which were deployed locally in my portal server.
Did a clean build.
Started the server.
It worked for me. Able to access my application. Rest of the projects which were not deployed as part of my local portal server, I will import them on need basis later.
I have imported my maven project in eclipse using Import Maven project. It got import in eclipse project explorer, but all the source folder are opening as files and folders, its not opening as java source folder. Since its opening as files and folder, it doesnot have compilation unit, found very difficult to code using it.
What do I need to do inorder to make the source folder as java source folder so that I can code easily?
Select the project and from the context menu choose Maven -> Update Project Configuration (This menu item gets reworded across various maven releases so look for something similar). You may also need to choose Update Dependencies.
In the shell/command line, execute mvn eclipse:eclipse
I have one IntelliJ project and I want to open it in Eclipse, so what should I do?
There is an export to eclipse option in Intellij Under file menu.
This option will generate you the necessary .project and .classpath files that will be used by eclipse. Personally, I would remove any IDE dependencies using some dependency management systems like Maven or Apache IVY. ( Is system the right term?)
I had the same issue and (I don't have Intellij) but doc_180's comment pointed me in the right direction. Here is a simple solution. In Eclipse create a new blank Android project. Copy the .project and .classpath files and the .settings folder to the Intellij folder. Edit the .project file and change the name of the project.
You should now be able to Import the project in Eclipse by right clicking and selecting "Import->Existing Project into Workspace".
I see this is an old question, but thought I should add this answer for others Googling it like me ;)
Without access to IntelliJ to export and convert the project, try the following.
In STS or Eclipse create an empty project first, then, select File -> Import and choose General -> File System. In the resulting dialog box, select the root folder of the IntelliJ project as source and the empty project as the destination.
For unit tests, add the test folder as a source folder to the build path (right-click on the folder, select Build Path -> Use as Source Folder).
The projects I import this way run without any further modifications, including the tests.
Eclipse and Intellij create different project structure each other (Output path, Source Code etc...). You can export the current project to Eclipse environment.
File -> Export -> Project to Eclipse
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 ;)
