No, I spoke to soon. What I meant is that calling getMethods() the JavaParser will traverse the AST tree internally, in a similar way that your code does.

Hey Rafael,
I don't see how using AST is different from what I proposed. When you have a JavaSource object, the tree was already traversed and the options are just there.

Hi George,
i dont think iterate over all methods is an option, im going to inspect very large applications(100K + lines of code) so id like to insist with AST.

Hi Rafael,
You don't need AST for your code. You can use the forge-parser API for that.
Cast your JavaSource to JavaClass and you can call javaClass.getMethods() to fetch the methods the JavaClass declares. Then iterate through them and you'll have your information.

Hi Ivan,
i need to visit AST, such as here: https://github.com/rmpestano/intrabundle/blob/master/src/main/java/br/ufrgs/rmpestano/intrabundle/jdt/StaleReferencesVisitor.java
that can be done with forge parser?
I have no issues with the tests.
One thing that would solve the problem would be to provide module.xml inside the plugin which would override default module.xml , something like is done with jboss-deployment-structure in Java EE apps, is that possible?

Hi Rafael,
Most probably the reason for the class cast exception is that you have declared compile dependency to both the Forge parser and the jdt-core module. The parser module has itself dependency to jdt core. Both modules are loaded in separate classloaders. So maybe Forge loads the CompilationUnit class in different classloader than yours.
So I would expect that the provided scope should work, not sure why it failed.
I would suggest following what George asked earlier in this thread: 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
Besides the classloading issues, the Forge parser API is much more intuitive to use than JDT core. The downside is that not all of the JDT core is wrapped. But I hope that it has everything you need.
Cheers,Ivan

Rafael,
Try adding your JDT dependencies as provided. I'm afraid Forge 1 won't handle conflicting classes very well. This is fixed in Forge 2.

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)

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?
