classpathHell - Classpath Mayhem Detector

Statically typed implementation of portingle/classpathHell

It's far too easy to end up with multiple copies of a class or resource on your classpath leading to runtime errors that, due to classpath ordering instability, might not show up until late in your release cycle, or possibly even production.

classpathHell is a gradle plugin that breaks the build if there are classpath collisions.

Configuration

classpathHell {
  configurationsToScan = [configurations.runtime]
  suppressExactDupes = true
  resourceExclusions = ["somePath/", ".*class"] // pattern matches on resource path
  resourceExclusions.addAll([".*/", "anotherPath/.*"])
  artifactExclusions = [".*hamcrest-core.*"]
}

./gradlew checkClasspath

build.dependsOn(["checkClasspath"])
