Class Retrofitter
java.lang.Object
org.objectweb.asm.tools.Retrofitter
A tool to transform classes in order to make them compatible with Java 1.5, and to check that
they use only the JDK 1.5 API and JDK 1.5 class file features. The original classes can either be
transformed "in place", or be copied first to destination directory and transformed here (leaving
the original classes unchanged).

args
- a directory containing compiled classes and the ASM release version.- Throws:
IOException
- if a file can't be read or written.

classesDir
- a directory containing compiled classes.version
- the module-info version.- Throws:
IOException
- if a file can't be read or written.

verify
public void verify(File classesDir, String expectedVersion, List<String> expectedExports, List<String> expectedRequires) throws IOException Verify that the class files in the given directory only use JDK 1.5 APIs, and that a module-info class is present with the expected content.- Parameters:
