Re: [pde-build-dev] PDE.build & maven classpath computation
|
FYI, I have incorporated the MavenGenerator into the maven-pde-plugin, but I needed to make a few tweaks to the code. I also need to cleanup my code so I don't embarrass myself and set the permissions on a new svn repo and then you all can check it out. Assuming no one bothers me in the next couple of time units then I can get this out.

Tom,
For the compiler, in pde.build we use
the batch compiler via the JDTCompilerAdapter (which extends Ant's DefaultCompilerAdapter)
which calls Main.compile. The JDTCompilerAdapter also handles us
providing access rules to the compiler. Unfortunately I don't know
anything about setting up the compiler using a class loader.
MavenGenerator does currently find all
the jars under the given directory. While testing, I pointed it to
a subdir of the repo (/org/eclipse). MavenGenerator is just an example
and we will want a better way to come up with the list of jars to consider
in the state. I'm not sure that getting them from maven's list of
dependencies is the answer since this implies recording dependencies in
the pom while we are trying to base them on the manifest.

Thanks!
I started taking a look at the way the Eclipse compiler is currently
offered as an option in Maven. This is purely as a replacement of
Sun's javac. It is implemented as a Plexus component (Plexus is
Maven's component framework).
See:
https://svn.codehaus.org/plexus/trunk/plexus-components/plexus-compiler/plexus-compilers/plexus-compiler-eclipse/src/main/java/org/codehaus/plexus/compiler/eclipse/EclipseJavaCompiler.java
While the Eclipse docs talk about calling the batch compiler by
invoking org.eclipse.jdt.internal.compiler.batch.Main.compile, the
Plexus wrapper sets up some kind of environment and calls the Compiler
class directly. The classes that make up the classpath are put into a
classloader and this classloader is passed to the compiler. Can
anybody tell me (or point me at some info on) how to pass the correct
classpath configuration in this setting ?
Also, I browsed through your MavenGenerator. Do I understand correctly
that this will find all jars in the local repository for each compile
? Maven can provide you with a list of the relevant jars from its list
of dependencies.
