How can I get this to work? Thanks in advance for your feedback! I've found a number of issues on the web that seem similar to this, namely this one, but I don't really understand the answer. Run with -info or -debug option to get more log output. Run with -stacktrace option to get the stack trace. > : PKIX path building failed: .SunCertPathBuilderException: unable to find valid certification path to requested target > Failed to list versions for :ForgeGradle. > Could not resolve all artifacts for configuration ':classpath'. gradlew genEclipseRunsĮrror: FAILURE: Build failed with an exception.Ī problem occurred configuring root project 'forge-1.12.2-14.-mdk'. Whenever I run either of the following commands, Gradle returns the same error. I am attempting to set up Eclipse and Minecraft Forge with Gradle on Mac OS X so I can try my hand at modding.
