Jake, I got around this problem while attempting to compile with JDK
1.3. What I did was modify the Plexus JavaCompiler to use a file list
instead of the command line. The challenge is creating a mojo
component. Here's the code in case you want to do the same:
File fileList = new File(config.getWorkingDirectory(), "sourceFiles");
try {
FileWriter fwriter = new FileWriter(fileList);
for ( int i = 0; i < sourceFiles.length; i++ )
{
fwriter.write(sourceFiles[i] + "\n");
}
fwriter.flush();
args.add("@" + fileList.getName());
} catch (IOException e) {
e.printStackTrace();
}
Contact me directly if you need help doing this. HTH.
