specifying java version to use in the README?

[PerrineGilloteaux]

Java 8 does not seems compatible, It went fine with java 14, I am guessing java 11 as well :) Many thanks for this great extension! (in case anyone got the same problem that was the bug messge when building with gradlew:

* What went wrong:
Execution failed for task ':compileJava'.
> Could not resolve all files for configuration ':compileClasspath'.
   > Could not resolve io.github.qupath:qupath-gui-fx:0.3.0-SNAPSHOT.
     Required by:
         project :
      > No matching variant of io.github.qupath:qupath-gui-fx:0.3.0-SNAPSHOT:20210701.045802-9 was found. The consumer was configured to find an API of a library compatible with Java 8, preferably in the form of class files, preferably optimized for standard JVMs, and its dependencies declared externally but:
          - Variant 'apiElements' capability io.github.qupath:qupath-gui-fx:0.3.0-SNAPSHOT declares an API of a library, packaged as a jar, and its dependencies declared externally:
              - Incompatible because this component declares a component compatible with Java 11 and the consumer needed a component compatible with Java 8
              - Other compatible attribute:
                  - Doesn't say anything about its target Java environment (preferred optimized for standard JVMs)
          - Variant 'javadocElements' capability io.github.qupath:qupath-gui-fx:0.3.0-SNAPSHOT declares a runtime of a component, and its dependencies declared externally:
              - Incompatible because this component declares documentation and the consumer needed a library
              - Other compatible attributes:
                  - Doesn't say anything about its target Java environment (preferred optimized for standard JVMs)
                  - Doesn't say anything about its target Java version (required compatibility with Java 8)
                  - Doesn't say anything about its elements (required them preferably in the form of class files)
          - Variant 'runtimeElements' capability io.github.qupath:qupath-gui-fx:0.3.0-SNAPSHOT declares a runtime of a library, packaged as a jar, and its dependencies declared externally:
              - Incompatible because this component declares a component compatible with Java 11 and the consumer needed a component compatible with Java 8
              - Other compatible attribute:
                  - Doesn't say anything about its target Java environment (preferred optimized for standard JVMs)
          - Variant 'sourcesElements' capability io.github.qupath:qupath-gui-fx:0.3.0-SNAPSHOT declares a runtime of a component, and its dependencies declared externally:
              - Incompatible because this component declares documentation and the consumer needed a library
              - Other compatible attributes:
                  - Doesn't say anything about its target Java environment (preferred optimized for standard JVMs)
                  - Doesn't say anything about its target Java version (required compatibility with Java 8)
                  - Doesn't say anything about its elements (required them preferably in the form of class files)

Best and many thanks for your great tutorial at th EMBO course today!

Ah, thanks! You're right, Java 11+ should work.

It should be possible to make it work with Java 8 via a gradle toolchain (well, the toolchain will force gradle to download a compatible Java version) - I did this with the main QuPath repository, but not with the extensions. So I'll leave this issue open as a reminder we should update both the readme and the toolchain to maximize the chances it will work.
