Question

A little know feature of the Eclipse’s Java compiler is that you can run it from the command line.

This works well (after patching plexus-compiler to use the latest release).

My problem: The stack traces are different when I compile the code from the command line. For example, when I run the compiler in the IDE, I get this output:

     at com.some.Foo.method(Foo.java:312)

but when I compile the code from the command line, I get this:

     at com.some.Foo.method(com.some.Foo:312)
                            ^^^^^^^^^^^^

What’s going here???

Analyzing the class files with javap gives:

SourceFile: "Foo.java"

and

SourceFile: "com.some.Foo"

Any ideas what might cause this?

Answer 1

I’m using a patched plexus-compiler-eclipse (I patched the POM to include the 3.7/Helios compiler).

In the class EclipseJavaCompiler.CompilationUnit, there is this code:

    public char[] getFileName()
    {
        return className.toCharArray();
    }

which should be

    public char[] getFileName()
    {
        return sourceFile.toCharArray();
    }
