Issue building TFM #2147

Closed ghost closed 6 years ago

ghost commented 6 years ago

I get these errors when I try to build TFM. Any solutions to resolve this issue?

What branch are you trying to build?

ghost commented 6 years ago

The branch i'm using is TFM1.12-Alpha

Wild1145 commented 6 years ago

Have you made any changes to the code?

ghost commented 6 years ago

No. All I did was clone TFM and add the lib folder. No errors appear after compiling, but the error above for some reason keeps showing and failing to build when I build the plugin.

JeromSar commented 6 years ago

What version of Java are you building with? We recommend at least JDK 1.7

Wild1145 commented 6 years ago

@poppy44 The alpha branch contains fully automated maven building. Try running a clean & build instead of just a build, if not re-clone it and DO NOT add the lib folder this time, just launch the project and compile it with maven.

ghost commented 6 years ago

I'm using JDK version 1.7.0_80

ghost commented 6 years ago

oh Wild I forgot to mention. When I was building it, I was selecting clean and build the whole time.

ghost commented 6 years ago

@Wild1145 how do I compile it with maven? when I cloned TFM from git, it also came with the lib folder.

JeromSar commented 6 years ago

I see the issue. Whilst TotalFreedomMod should be compiled with JDK 1.7 (as indicated in pom.xml), it actually uses JDK 8 functionality (namely java.util.function.Function). This is a bug, but there's no fix right now. For now, I recommend upgrading to JDK 8.

ghost commented 6 years ago

It works now, seems the older version of JDK I used was causing it to fail at building. Thanks for the help. :)
