I have a problem with Netbeans simply not recognizing Javadocs in external libraries. I've gone into the library path and specified a valid javadoc path (Netbeans accepts the path without error). But even after re-building/opening closing Netbeans, I still get the "Javadoc not found" error for all items in the library.
I'm stuck on where to go since there is no error message, and I can browse the docs using a web-browser. Any ideas?
The version of NEtbeans is 6.5.1
The files are uncompressed in a directory that has been added to the the Javadoc tab of the properties for the library. The library works as expected.
I've tried clearing the Netbeans cache to no effect.
I got it working. I deleted the library, the re-created it added the Javadocs. Now it works perfectly.
Could you please be more specific: What is your version of NetBeans? Where are those javadocs located? Are they unpacked in a separate folder, in a zip file, in jar file?
Here is a working solution for NetBeans 6.5 for an example:
Go to Project Properties > Libraries dialog
On "Compile" tab press the "Add JAR/Folder" button and locate your library
On "Compile" tab press the "Edit" button with your library selected
Add path to either: a) docs folder of that library, containing index.html and the rest of the files; b) zip file, containing that libraries docs folder;
It should work without re-building your project or restarting NetBeans.
If you have created a custom library, it can be edited in a very similar fashion through "Tools > Libraries"
Sounds similar to a problem i had recently, turned out all i had to do was delete the cache to force NetBeans to rebuild.
If #slink84's suggestion fails to help, you might try #dr Hanibbal Lecter's method from my question on stackoverflow

I have a GMF editor and an Acceleo UI project that I would like to bundle in a single plugin. That's not the matter though.
You see, when executed in the runtime (Run as > Eclipse Application), both the GMF editor and the Acceleo UI project work fine and dandy.
However, when exported as plugins and installed into Eclipse, only the GMF editor will work. The Acceleo UI item WILL show up in the context menu, and it will create the target folder for the files. But this folder will be empty.
Is there a reason why one plugin would work properly while the other does not? Is there any additional configuring that must be done in the Acceleo UI for it to work outside the runtime?
Searching the Eclipse Forums, I found something about adding a line 'outputFolder="${target.folder}"' to a file "acceleo.build", but I can't find neither the file nor the line anywhere.
Any help would be greatly appreciated. I'm working on Eclipse Mars with version 3.6.3.201602090916 of Acceleo.
So, I know nobody ever replied to me, but I found out the problem so I might as well post it in case someone runs into the same issue in the future.
The issue was that Acceleo needs a file with extension .emtl to work. This file wasn't showing up anywhere when exporting the plugin, though. I thought it was failing to compile it (as the .etml is actually a compiled form of the .mtl file).
After some digging, I found out Acceleo does actually create said file, but it doesn't put it in the same place where the .mtl is - it actually places it in a folder called "bin", which isn't created by default when exporting the plugin. In order to see this "bin" folder, I had to mark it in "Build Configuration", in the build.properties file.
Then, I manually copied the .etml in "bin" to the plugin's "main" folder (where the .mtl file resides) and that was it, it worked like a charm.
I'm using the Android Developer Tools wrapper of Eclipse, and the EGit git plugin for Eclipse. I'm having a problem where I'm generating Javadoc, but I can't find it in the package explorer.
I go to Project->Generate Javadoc.
I'm using C:\Program Files\Java\jdk1.7.0_51\bin\javadoc.exe as my Javadoc command, and I select the package I want to generate Javadoc for.
I select the standard doclet with the following destination, where ReverseSentence is my package.
C:\Users\myname\workspace\ReverseSentence\doc
I check "open generated index file in browser", and generate the javadoc. It generates the Javadoc with no errors, and the index shows up in the main section of eclipse. However, the files don't show up in the package explorer.
I searched in the workspace through opening up the folder, and inside workspace\ReverseSentence there is a folder doc, which contains the proper Javadoc. However it isn't showing up in the package explorer.
How do I make it show up in the package explorer? When I used the regular version of Eclipse in the past (not the android developer tools wrapper), the Javadocs showed up there automatically.
What I've tried:
refreshing the project
closing and restarting eclipse
generating the Javadoc with an older version of the Javadoc command, which was what I was using in the other version of eclipse last time it worked (jdk1.6.0_43)
deleting the doc folder, recreating it, then trying to generate the javadoc in it (it generated in it but did not show up)
unchecking the filters which hide some things in the package explorer, (as shown how to do here: How can I get Eclipse to show .* files?)
I think that the problem is the destination folder/directory for your Javadoc files once they are generated. I encountered this same problem and discovered (finally) that the Javadocs were getting sent to a different folder than my package files were in. They went to the workspace folder I thought held all of my code also, but the code was going into a different repository. Maybe try looking for your code's location and then seeing if the generated Javadocs are landing somewhere else when they are generated. If this is the case, then the fix is to regenerate and send to the code's directory. This way, Package Explorer should be able to find and display them. Hope this helps!
Did you try by refreshing the workspace or re-opening the eclipse !?
Check the filters in the settings of the explorer. If something does not show up, usually the filter hides it. The filter can be accessed in the drop down menu of Package Explorer.
For almost every library I've come to see a link of the JAVADOCS jar to be downloaded, plain and simple. Why There is no jar for SWT ? and if there is why it's not on their website ..
Please note that I know there is a version in Eclipse help, and there is an online version, which I can't link to cause It doesn't validate cause it's in php ! no Index.html found
Though that's not what I'm looking for I tried it, I'm using SWT.jar and I want to attach the javadocs jar to it so when CTRL+Space and highlight a method I just see the docs right away beside etc you know..
Anyway Because I think SWT is so great I feel like there is a simple way to do that and I just can't see it maybe. if there is nothing I think I should file a feature request or somethin' to them.
Ok I kinda knew this question was not going to get much interest, so I gave it another try and I came back cause I don't want anyone to waste 1 hour of trying to figure out something like that..
Download the swt zip
Go to eclipse and load existing project
you'll find src.zip in that project
unzip src.zip and copy the folder "org" org\eclipse\swt..
paste that folder in src (inside the project)
select org folder in eclipse then go to project >> generate javadocs
If you're in windows you probably going to press on (Configure) to pick up the Javadoc.exe file it's in the C:\programFiles\java\jdk-xyz\bin\
choose where you want to drop the doc files, next then finish
ok, just go to the files and zip it, P.S zip the files don't zip the folder which contains the files cause when you load the docs as archive and validate it won't see the index.html
if you want to know how to load the archive, google it's in (in project properties>> java buildpath >> libraries tab >> swt jar >> add jar >> add your SWT.jar then expand and edit the javadoc location..
That was Robo detailed I know, I just don't want someone to read this and still can't do it
The suggested way to develop SWT apps is by following the instructions at Developing SWT applications using Eclipse. Each download page of eclipse includes an SWT section with SWT source complete zips.
The second way as mentioned is to look in your eclipse/plugins directory and use the 2 arch compatible jars provided there:
org.eclipse.swt.gtk.linux.x86_64_3.7.0.v3735b.jar
org.eclipse.swt.gtk.linux.x86_64.source_3.7.0.v3735b.jar
The source jar can be attached so as to provide javadoc. The javadoc (for most of the API shipped with eclipse) is stored in the eclipse/plugins/org.eclipse.platform.doc.isv_3.7.0.v20110602-0800.jar jar. If you unzip that, it should be in reference/api
I know that Eclipse is setting up a maven repository, although a quick scan for org.eclipse.swt only found 3.6.2 binaries and source. See http://maven.eclipse.org. They're still in they trail phase.
I had a problem with finding Java docs in Eclipse. I seem to have fixed the problem, but I'm posting this for two reasons: I would like to know why I had the problem in the first place and perhaps my method of fixing it might be useful to someone else having a similar problem.
I created a simple Java project in Eclipse (Helios on Windows 7) and selected the JavaSE-1.6 JRE. Then I created a source file and imported java.util.GregorianCalendar. When I hovered over GregorianCalendar, I was getting the message:
This element has no attached source and the Javadoc could not be found in the attached Javadoc
None of the methods of GregorianCalendar seemed to have any Javadoc, either. Other standard Java classes (even others in java.util, like ArrayList) didn't have this problem; only GregorianCalendar. Everything seemed set up properly in the project settings. The Javadoc location set in the Java Build Path was http://java.sun.com/javase/6/docs/api/.
I managed to restore correct behavior by temporarily switching to JavaSE-1.7 and then back. Evidently something got reset and all is well. While I'm happy that things are now working, I don't like being clueless as to how they got messed up in the first place.
Can anyone provide any insights into this?
I think general support relies on the presence of a src.zip in your JDK directory, which is detected when you autosearch a directory for Java installations. It could be missing. Not sure if online Javadocs are used.
I'm using Eclipse Juno on a Windows 7 64-bit (with a 32-bit JDK) but i think it will also apply to your Eclipse version:
Download JDK docs zip file to your Desktop folder;
Right-click on the file, choose Properties and unblock it;
Move the file to a location of your choice. I normally move it to the JDK folder;
Open Eclipse and go to Window->Preferences->Java->Installed JREs;
Select your JDK installation and press Edit;
Select the rt.jar file and click "Javadoc Location..." button;
Select the "Javadoc in archive" radio button;
Set the archive path by browsing to the JDK docs zip file;
Set the "Path within archive" to "docs/api" (without the quotes).
Enjoy! ;)
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.

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 ;)
