如何在 Red Hat JBoss Developer Studio 中启用 JDK 15？

Question

I'm using Red Hat JBoss Developer Studio 10.4.0.GA (also tested with CodeReady 12.17.0.GA), and would like to upgrade to JDK 15.

But even with the new version installed, it is not available to be setup as default JRE.

I tried some eclipse instructions to JDK 15 ( #1 and #2 ), but without success with JBoss.

Does anyone have a tip?

Thank you

Use Eclipse 2020-09 (4.17)

Answer 1

Your error same with this error: Target is not a JDK root. System library was not found. Eclipse Oxygen 4.7 + Java9 error

So you have to find a support extension if its existing and available.

Answer 2

确保您安装了带有Java 15 Support for Eclipse 2020-09 (4.17) 的 Eclipse 2020-09 (4.17) 。
