Subject [jira] [Commented] (FLINK-924) Extend JarFileCreator to automatically include dependencies
Date Wed, 18 Jun 2014 19:32:29 GMT

    [ https://issues.apache.org/jira/browse/FLINK-924?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14036236#comment-14036236

Robert Metzger commented on FLINK-924:

I would go for white-listing the package that contains the user code and add a API for the
user to add additional packages to the whitelist.

>                 Key: FLINK-924
>                 URL: https://issues.apache.org/jira/browse/FLINK-924
>             Project: Flink
>          Issue Type: Improvement
>            Reporter: Ufuk Celebi
>            Assignee: Mingliang Qi
>            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.
