Can someone help me with this? some people say you can fix this problem by deleting metadata folder but it resets a lot of configurations and to be honest i dont remember how to confing some things back to work properly on some projects, can someone identify the problem if i leave the .log text? because i dont understand whats the problem is
im looking for a solution to not delete the whole folder since i dont know how to restore some configurations back on the project i want to run, its an old one
Deleting the
.metadatafolder is almost always the wrong thing to do. This is pretty simple, though--Oxygen was the 2017 release, before Java 9 released, and Java releases since then have removed APIs from the Java standard runtime--including the one you're seeing errors about. As this is a release from nearly 7 years ago, just go get the current one from https://download.eclipse.org instead.
