Java Maven builds have failed without any changes to the build scripts.

Resolution

We've added Maven Wrapper support to our Java Buildpack. If your build output has any lines matching:

 remote: -----> Executing: ./mvnw -B ...

Can you try either:

  • Removing the mvnw script from the repo
  • Adding maven.version=3.3.9 to the system.properties file.

If neither of these solutions fixes your problem, please can you raise a new support ticket.
