Eclipse Compiler Classpath Ignored [message #755410]

Hello,

i have an RCP application which uses the Compiler API to compile java source programmatically. At the moment i use the standard java compiler with the classpath from the different plugins (paths to the external libs and binarys).

Vector<String> optionList = new Vector<String>();
optionList.addElement("-classpath");
optionList.addElement(my paths);

JavacTool compiler = com.sun.tools.javac.api.JavacTool.create();
.........
compiler.getTask(out,fileManager,null,optionList, null,Collections.singleton(sf)).call();
.......
This works as expected.

However if i try to use the Eclipse compiler instead:

JavaCompiler compiler = new EclipseCompiler();
..........

compilation errors are thrown because of the missing classpath.
Is this a bug of the Eclipse compiler in combination with Compiler API or did i do something wrong?

Apropos is there another way to calculate the classpath for the compiler (API which gives me the whole classpath of the RCP application and the embedded plugins and libs)?

Thanks in advance for any hints!

Are the classpaths (my paths) absolute?

Yes, the classpath paths are absolute paths. They are accepted in the eclipse compiler
if i use them without the compiler API.

I'm still struggling with the classpath when using the Compiler API with the Eclipse compiler. Has anybody used successful the compiler API+Eclipse compiler+classpath (as argument)?
If so are there any examples available so that i can compare the example with my config.?
