STS + Roo problems

[duckbill]

Hi,

For starters, I have to say that Roo looks really promising.

Unfortunately I have a problem with importing a Roo-generated (Roo 1.0.0RC1) project into STS (2.1.0RC1). This is described below.

I've succesfully created a small project with a few entities and controllers. Then ran mvn eclipse:eclipse to create an eclipse project out of it, and imported that into STS. I can actually deploy the application both via STS and mvn tomcat:run. Using Maven 2.2.0.

In the problems view, I always end up having a bunch of Java problems pointing to Roo-generated .aj files. E.g. "capacity cannot be resolved or is not a field" for "Room_Roo_JavaBean.aj". I have enabled m2 dependency management.

What might be causing this? AJDT, Roo or Eclipse? Compiler/buildpath issues maybe?

Thanks for your help,
Jukka

I am also facing the exact problem. I have created the roo project using STS (2.1.0RC1) from the integrated roo shell.

Even after enabling m2 dependency management, there are still hundreds of compilation errors. I could deploy the app and run it successfully, though.

Does anyone have a solution for this issue ?

Best Regards,
Ram.

I'm seeing the same issues here.

Running Linux x64 edition of latest 2.1 STS.

Interesting thing is if I back down to: 2.1.0.RC1-e3.5, the problem isn't there.

I don't know if this is a problem with the latest STS Tool set, or with the latest roo plugin....

I can recreate it very easily by simply creating a new project, a couple of entity classes, and controllers. Somewhere along the way, it starts to fall apart, generates errors regarding the *.aj files and artifact resolution.

I'm backing down to the RC1 until this is resolved.

Small Update:

If I use: 2.1.0.RC1-e3.5 as a base, and then update to the latest release using the update site, this problem doesn't seem to occur, or at least I can't reproduce it.

What's interesting is this. The RC for e3.5 is using this jar:

org.eclipse.ajdt.core_2.0.0.e34x-20090623-1400.jar

The Release is using:

org.eclipse.ajdt.core_2.0.0.e35x-20090624-1600.jar

And the error being thrown before all havoc starts seems to be related:

java.lang.NoSuchMethodError: org.eclipse.ajdt.core.parserbridge.AJCompilationUn itProblemFinder.getCompilerOptions(Ljava/util/Map;ZZ)Lorg/eclipse/jdt/internal/compiler/impl/CompilerOptions;


Any ideas?

java.lang.NoSuchMethodError: org.eclipse.ajdt.core.parserbridge.AJCompilationUn itProblemFinder.getCompilerOptions(Ljava/util/Map;ZZ)Lorg/eclipse/jdt/internal/compiler/impl/CompilerOptions;

I resolved this error by going with STS and none of the Groovy crap. Seems as though the Groovy plugin was the culprit.

You could take a peak at http://forum.springsource.org/showthread.php?t=75966 for more information that might help.

I'm facing the exact problem. Is this problem solved?

I'm using 2.1.0.SR01-e3.5 without groovy support (all latest versions from the download site and installed unmodified) and still have the same problem. Two ways can reproduce this problem.

#1 (from within STS)
1. create Roo Web App within STS
2. follow the normal procedure: install jpa, new persistence class, add controller automatic
3. everything is OK until you right click on the project and select the menu maven>update the project configuration and execute
4. now the exact problem described in previous posts appears.

#2 (from within command line)
1. start a terminal console and follow the normal procedures to to use Roo to create a simple CRUD webapp
2. execute mvn eclipse:eclipse
3. import the project into workspace with STS
4. the problem appears.

@kenyth,

I am sorry you have such a rough experience with STS. I use the same version and don't have these problems. However, I know the AJDT team has fixed a few bugs for us recently and not all of them are included in the latest official STS version yet. What you can do is to try installing a nightly snapshot of AJDT into a fresh install of STS.

Also, make sure to use project > clean in STS if you should encounter incremental compilation problems. These problems should be fixed with the next official release of STS and AJDT.

Cheers,
Stefan

Yes. project > clean helps sometimes. Thanks for your reply!
