error: has been compiled by a more recent version

[andrewarrow]

Tried to run ./gradlew -p samples installDist from README and got:

> Task :mosaic:mosaic-runtime:compileKotlin FAILED
e: java.lang.UnsupportedClassVersionError: 
androidx/compose/compiler/plugins/kotlin/ComposeComponentRegistrar
has been compiled by a more recent version of the Java Runtime
(class file version 55.0), this version of the Java Runtime only recognizes
class file versions up to 52.0

Found https://stackoverflow.com/questions/47457105/class-has-been-compiled-by-a-more-recent-version-of-the-java-environment

Researching this now, will post an update here if I solve it.

Couple different ways to do it. I ended up installing android studio to get java11 and then added:

cd /Library/Java/JavaVirtualMachines
ln -s /Applications/Android\ Studio.app/Contents/jre java11

all I add in JavaVirtualMachines directory before was adoptopenjdk-8.jdk.

Once I added java11 and set:

export JAVA_HOME="/Library/Java/JavaVirtualMachines/java11/Contents/Home"

Then ./gradlew -p samples installDist worked without error.
