Ufuk Celebi created FLINK-924:
---------------------------------
Summary: Extend JarFileCreator to automatically include
dependencies
Key: FLINK-924
URL: https://issues.apache.org/jira/browse/FLINK-924
Project: Flink
Issue Type: Improvement
Reporter: Ufuk Celebi
Priority: Minor
We have a simple {{JarFileCreator}}, which allows to add classes to a JAR file
as follows:
{code:java}
JarFileCreator jfc = new JarFileCreator(jarFile);
jfc.addClass(X.class);
jfc.addClass(Y.class);
jfc.createJarFile();
{code}
The created file can then be used with the remote execution environment, which
requires a JAR file to ship.
I propose the following improvement: use [ASM|http://asm.ow2.org/] to extract
all dependencies and add create the JAR file automatically.
There is an [old tutorial|http://asm.ow2.org/doc/tutorial-asm-2.0.html] (for
ASM 2), which implements a {{DependencyVisitor}}. Unfortuneately the code does
not directly work with ASM 5, but it should be a good starting point.
