“Could not find or load main class java.se.ee” while running sdkmanager --licences

Question

When building my project on android studio, it asks me to accept the license agreements and complete the installation of the missing components using the Android Studio SDK Manager.

When I run "./sdkmanager --licenses", I have the "Could not find or load main class java.se.ee" error.

I found a lot of similar issues on stackoverflow, but non of the solutions provided worked for me.

I already tried: 1- downgrade to java 8

2- export JAVA_OPTS='-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'

3- change sdkmanager file by adding : DEFAULT_JVM_OPTS='"-Dcom.android.sdklib.toolsdir=$APP_HOME" -XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'

Answer 1

I had the same issue.
And solved by following the below steps:

1) Install java 8

2) Run command in terminal

unset JAVA_OPTS

3) Then run command in terminal

./sdkmanager --licenses

Answer 2

Well, it's been 4 months since you asked the question. You must have found the answer, but here is a way easy solution for others who are still looking for it:

JAVA_OPTS='-XX:+IgnoreUnrecognizedVMOptions'

And, Voila the issue is solved!

Why this solved the problem?

Well I don't know the exact reason but, I also don't know why we tend to add java.se.ee through "--add-modules java.se.ee", I tried removing it and error was gone! Maybe because java11 removed EE module, and it was depreciated in java10.

It was just a blind shot which worked!, If anyone knows the proper reason please comment it out!

Answer 3

Unsetting JAVA_OPTS worked for me.

unset JAVA_OPTS
sdkmanager --list
dkmanager "platform-tools" "platforms;android-28"
