Recommended Posts

This is the error that I'm getting.

WARNING: Unknown module: cpw.mods.securejarhandler specified to --add-exports

Tried various java versions,   8 and 16 to no avail. even tried bellsoft liberica full jre  and openjre


No clue what is going on and why there are such problems with Java now, seems like Oracle took their ball and wants to go home with the Java project.

So many issues with various versions of it.  Any advice? Thanks,.

Unknown module securejarhandler implies that some libraries were missed during the installation.

I suggest you redownload the latest installer and run it again.


I did download the latest forge-1.18-38.0.6-installer and installed it correctly into the right place.

Also downloaded  38.0.5 to test (didn't work) and downloaded 38.0.0

None of those worked.


It seems like the forge installer is not downloading all of the libraries.  I am looking in the versions folders and the forge folder is very small like under 1mb

do you know what is causing that?
