class file has wrong version 55.0, should be 52.0 #28

Closed gqqnbig closed 2 years ago

gqqnbig commented 3 years ago

As requested in README, I downloaded JDK 8 and build the repo. However Gradle refused to build.

$ export JAVA_HOME=~/jdk1.8.0_301/
$  ./gradlew build

Can you check the required JDK version?

Hi @gqqnbig it works with Java 1.8. If you execute java -version and javac -version, does it displays 1.8 for both?

Please, try to clean your dependencies after switch to the new environment: ./gradlew clean
