Unsupported major.minor version 52.0 about kscript

[holgerbrandl]

This is a Java version mismatch. Could you use JRE/Java8 instead of the outdated Java7? This will fix the problem.

It seems that you're either

1. having a version difference between javac and java in your shell
2. or one of your declared dependencies was compiled with java8 and your using java7 in your shell.

Since kscript does not ship any compiled code, it's nothing I could actually fix.

If this does not help you to solve your problem, could you provide the test.kts, so that I can have a more in-depth look?

Hm, I'm on java version 1.8.0_91. There is another library that is working fine:
https://github.com/andrewoma/kotlin-script
I'l just use that,

Would you mind running

echo $JAVA_HOME
$JAVA_HOME/bin/javac -version
java -version
javac -version

in your terminal and attaching the result to this ticket?

I could imagine a version mismatch in your setup since kotlinc is using JAVA_HOME to locate the compiler, but kscript was just running java from your PATH. If now the latter is v1.7 and the former pointing to an 1.8 installation, it would explain your problem.

The problem has been solved (see commit above) and simply reinstalling kscript with curl as indicated in the READM.md should fix it.
