Normalize path (fat jar creation) fails because file path is too long

Old Forum

the attempt to create a fat jar calls normalize path with fails because the path name is too long.

task: jar {

manifest {

attributes ‘Implementation-Title’: ‘stroy’, ‘Implementation-Version’: version

from { configurations.runtime.collect { it.isDirectory() ? it : zipTree(it) } }

} }

error:

Your code is wrong. You have:

jar {
   manifest {
     attributes 'Implementation-Title': 'stroy', 'Implementation-Version': version
     from { configurations.runtime.collect { it.isDirectory() ? it : zipTree(it) } }
   }
 }

It should be:

jar {
   manifest {
     attributes 'Implementation-Title': 'stroy', 'Implementation-Version': version
   }
  from { configurations.runtime.collect { it.isDirectory() ? it : zipTree(it) } }
  }

@Luke: ‘from’ placement isn’t related to the problem. Generated names of the temporary files are too long. ext4 file system, for instance, has a maximum of 255 characters.

Do you have a self contained project that exhibits this that I can use?

Looking at this with fresh eyes… I think the problem is that from does not deal with a collection of zipTree() objects correctly.

However, I cannot reproduce this with Gradle 1.3.

@Luke: Here’s one: http://goo.gl/pS2ky Try to run ‘gradle fatJar’ on an ext4 partition.

Hello Eugene,

I just copied your script into a build.gradle file. Unfortunately I can’t reproduce the issue you’re running into on a ext4 partition.

cheers, René

For such problems, you can use Long Path Tool as well, it works good I will say.
