Gradlew genIntelliJRuns leads to java.lang.NullPointerException

RedRelay · June 26, 2019, 6:37pm

Hello there,

I’ve just trying to do my setup again, but it does not work like expected.

I’ve followed the documentation in english to be sure to not dismiss any little elements badly translated (just in case)

When I use ./gradlew genIntelliJRuns I got the following error :

java.lang.NullPointerException

To get it work I had to remove .idea folder and run ./gradlew idea genIntelliJRuns
But it lead to an

Error:(38, 32) java: cannot find symbol
  symbol:   class JavaVersionCheckUtils
  location: package org.spongepowered.launch

when I build.

Do you have any clues ?

My environement

Windows 10
IDEA IntelliJ Community 19.1.3
Oracle JDK 1.8_211 (same issue with 1.8_212)
SpongeForge branch is “stable-7”

I am terribly sad when I use Java it takes sooo loong to get ready to code

Gradle 5 doesnt work with sponge. You need to use the one built into Intelij (i think its 4.7). Go to your gradle settings and make sure you are using the gradle built into intelij.

RedRelay · June 26, 2019, 7:53pm

Do you know how can I do it please ?
I thought using gradlew packaged with the forge repository will use the proper version.
By doing ./gradlew --version I got :

I missread the error. You seemed to be on the correct version

RedRelay · June 27, 2019, 10:34am

Weird things … yesterday just before go to bed after keep IntelliJ and my terminal open, I’ve decided to do a 20th try … and magicaly it worked :o

I’ve change nothing but it finaly works :o
I know it will not help people in my case, but maybe gradle had to do some background task before.

RedRelay · July 3, 2019, 11:30am

I’ve done the setup on an other computer (windows 10), and the issue is the same.
But it does not resolve itself. I think this is a real issue.
I’ve tried using Windows Linux Subsystem (WLSS), the issue remain the same

VcSaJen · July 3, 2019, 2:51pm

Yeah, got some weird inconsistent errors too the last time I tried to do this.

Grauldon · December 8, 2019, 6:09pm

I experienced the problem also and found my solution in this GitHub issue ForgeGradle#533.

There are several solutions offered, so be sure to read them all before trying one. I deleted a folder and didn’t need to since that did not solve the problem.
