Looks like Travis CI is failing:

You might have to delete recursively.

@eed3si9n I ended up replicating exactly the previous behavior by removing only files.

[joan38]

Thanks @eed3si9n. Are you planning to make a release out of this?

[eed3si9n]

Yea. Let's do it.

[eed3si9n]

Oh no did you use JDK 9+ stuff? I don't want sbt-assembly to require JDK 9+.

[error] /Users/eed3si9n/work/jarjar-abrams/core/src/main/scala/com/eed3si9n/jarjarabrams/Shader.scala:21:36: value readAllBytes is not a member of java.io.InputStream
[error]       Files.write(out, inputStream.readAllBytes(), StandardOpenOption.CREATE)

[joan38]

Yes.
Ok let me create another PR to do differently.

[joan38]

Have a look at #5

https://github.com/eed3si9n/jarjar-abrams/releases/tag/v0.2.0 is on its way to Maven Central.

Nice! Thanks @eed3si9n
