Unable to use aspectj in java library

Description of the problem / feature request:

When a project uses aspectj (aspectjtools-1.8.13.jar) in a java_library ijar fails with the error ‘Bad magic efbfbdef’

When the ijar utility is used separately the output is: … INFO: StripClass: org/aspectj/org/eclipse/jdt/internal/compiler/parser/UpdateParserFiles.class Bad magic efbfbdef

It seems that the ijar utility isn’t able to read the UpdateParserFiles class file properly or it contains an invalid magic number.

Due to this issue we aren’t able to migrate from Maven to Bazel.

Bugs: what’s the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

Checkout bazel project and build ijar

git clone “https://github.com/bazelbuild/bazel.git” cd bazel bazel build //third_party/ijar

Download aspjectj jar

mvn org.apache.maven.plugins:maven-dependency-plugin:3.0.2:get -Dartifact=org.aspectj:aspectjtools:1.8.13

Run ijar against aspectj jar

./bazel-bin/third_party/ijar/ijar -v ~/.m2/repository/org/aspectj/aspectjtools/1.8.13/aspectjtools-1.8.13.jar

What operating system are you running Bazel on?

MacOS Sierra

What’s the output of bazel info release?

release 0.10.0

Have you found anything relevant by searching the web?

If I only was a little less impatient… Aspectj released version 1.9.0 which doesn’t include the corrupt class file.

Ok, thanks. I’ll try to use maven_jar from a Skylark rule.
