gradle Could not target platform: 'Java SE 11' using tool chain: 'JDK 8 (1.8)'

  • I'm building ghidra according to the installation guide. Everything goes fine Until I get here.
  • Once I call $ gradle buildGhidra I get the following error:
> Could not target platform: 'Java SE 11' using tool chain: 'JDK 8 (1.8)'

This seems weird because I do have java 11:

$ java --version
openjdk 11.0.8 2020-07-14
OpenJDK Runtime Environment (build 11.0.8+10-post-Ubuntu-0ubuntu118.04.1)
OpenJDK 64-Bit Server VM (build 11.0.8+10-post-Ubuntu-0ubuntu118.04.1, mixed mode, sharing)

What am I missing?

Solution
    • It turns out that gradle was after all the one to blame.
    • Probably similar to this post, I upgraded to gradle-6.7.
    • Then, calling gradle-6.7 --version, without any JAVA_HOME change whatsoever, I got:

Gradle 6.7-rc-3

Kotlin:       1.3.72
Groovy:       2.5.12
Ant:          Apache Ant(TM) version 1.10.8 compiled on May 10 2020
JVM:          11.0.8 (Ubuntu 11.0.8+10-post-Ubuntu-0ubuntu118.04.1)
OS:           Linux 5.4.0-48-generic amd64

    Which probably "proves" gradle is indeed the one to blame
