I recently downloaded Mcreator and have so far managed to get it to the point in the setup where it says "Caching Decompiled Code" in the upper left hand corner. I do have a slow internet connection, but I left it for 6 hours and nothing happened. It just keeps saying "Setting up Mcreator," no errors or anything, and my JAVA_HOME path is set properly. I am on Ubuntu 18.04. I need help getting past this point and it would also be helpful if someone told me what "Caching Decompiled Code" does.
What are the contents of the console tab?
compWorkspace --refresh-dependencies Build info: MCreator 1.8.0, 64-bit, 15931 MB, Linux, JVM 1.8.0_181 ERROR: JAVA_HOME is set to an invalid directory: /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java Please set the JAVA_HOME variable in your environment to match the location of your Java installation. Task completed with return code 1 in 10678 milliseconds
I only just saw this now that you have mentioned it. But isn't /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java the correct directory?
No, the correct one should point to JDK, not JRE. Install JDK and modify your JAVA_HOME to fix this error.
When I type in 'sudo update-alternatives --config java' it gives me:
There are 2 choices for the alternative java (providing /usr/bin/java).
Selection Path Priority Status
------------------------------------------------------------
0 /usr/lib/jvm/java-11-openjdk-amd64/bin/java 1101 auto mode
1 /usr/lib/jvm/java-11-openjdk-amd64/bin/java 1101 manual mode
* 2 /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java 1081 manual mode
Press <enter> to keep the current choice[*], or type selection number:
Are any of these the correct one?
No, you need Java 8 JDK, but you only have Java 8 JRE and Java 11 JDK.
Where do I download that?
Google should have the answer for this. A quick search showed this page: https://www.digitalocean.com/community/tutorials/how-to-install-java-wi…
Or this page: https://tecadmin.net/install-oracle-java-8-ubuntu-via-ppa/
The second tutorial seemed to help me just fine, thanks.
