Hi Ivan
"Are you sure that changing the scope to compile won't fix the issue?"


When i use compile scope i got classcast exception,(full stacktrace also added below) but as soon i use org.eclipse.jdt.core as provided and add java-parser module dependency to my plugin module.xml everything works. I think its a classloading issue.

Here is the code:
private boolean verifyStaleReference(JavaSource source) {
        CompilationUnit comp = (CompilationUnit) source.getInternal();
        comp.getRoot().toString();
//todo verify services stale references
        source.getOrigin().toString();
        return true;
    }



full source code is here:https://github.com/rmpestano/intrabundle/blob/master/src/main/java/br/ufrgs/rmpestano/intrabundle/model/OSGiModuleImpl.java#L351

I've also tried jdt from this dependency:
<dependency>
      <groupId>org.eclipse.jdt</groupId>
      <artifactId>org.eclipse.jdt.core</artifactId>
      <version>3.7.1</version>
      <scope>compile</scope>
    </dependency>
i got same classcastexception.

stacktrace:
***ERROR*** Exception encountered: (type "set VERBOSE false" to disable stack traces)
java.lang.ClassCastException: org.eclipse.jdt.core.dom.CompilationUnit cannot be cast to org.eclipse.jdt.core.dom.CompilationUnit

Hi guys,

i need to access class AST, is that possible with forge-shell-api?


2014-02-10 11:41 GMT-02:00 George Gastaldi <ggastald@redhat.com>:

Hi Rafael,

Why do you need to access  org.eclipse.jdt.core.dom.CompilationUnit? You should only use the classes in java-parser-api that is already provided when you add a dependency to forge-shell-api. That said, forge-shell-api with the provided scope is the only dependency your module might need.

See https://github.com/forge/core/blob/1.x/dev-plugins/pom.xml as an example.

Best Regards,

George

Hi guys,

how can i add a module dependency to my plugin?(in forge 1.x)

I'm using JavaParser and i need to access org.eclipse.jdt.core.dom.CompilationUnit api which is available in javaparser module (org.eclipse.jdt.core-3.9.1.jar) which doesnt comes in default module dependencies[1].

in my pom.xml i use <dependency>
      <groupId>org.eclipse.tycho</groupId>
      <artifactId>org.eclipse.jdt.core</artifactId>
      <version>3.9.1.v20130905-0837</version>
      <scope>provided</scope> tried compile also
    </dependency>

but i receive ***ERROR*** Exception encountered: (type "set VERBOSE false" to disable stack traces)
java.lang.ClassNotFoundException: org.eclipse.jdt.core.dom.CompilationUnit from [Module "br.ufrgs.rmpestano.intrabundle:0.1-SNAPSHOT-35a537a5-1ab6-4b19-a253-03e3bbfae57d" from local module loader @1eac903 (roots: /home/rmpestano/projetos/forge/dist/forge-distribution-1.4.3.Final/modules,/home/rmpestano/.forge/plugins,/home/rmpestano/projetos)]

if i add(manually) org.eclipse.javaparser module dependency in my plugin module.xml everything works.

How can i tell forge that i need that dependency?
