Can you please explain how that method works?
1. What does the following block do?
for (File file : new File(emmaHome).listFiles()) {
if
(file.getName().startsWith("org.wso2.carbon.integration.core")) {
ArchiveManipulator archiveManipulator = new
ArchiveManipulator();
archiveManipulator.extract(file.getAbsolutePath(),
emmaHome);
} else if (file.getName().startsWith("emma")) {
emmaJarName = file.getName();
}
}
2. What does the following block do?
for (File file : new File[]{new File(carbonHome), emmaOutput}) {
FileUtils.copyFileToDirectory(new File(carbonHome +
File.separator + "lib" +
File.separator + "emma.jar"), file);
FileUtils.copyFileToDirectory(new File(emmaHome +
"gen_emma_coverage.rb"), file);
FileUtils.copyFileToDirectory(new File(jarList), file);
}
gen_emma_coverage.rb is inside the resources directory in the Maven module.
How does it get picked?
