问题
I'm trying to run the new Java 15 features under Eclipse 2020-09.
I have installed OpenJDK 15 and set it under "Installed JRE":
Nevertheless I cannot set this version as compiler version (only till version 14):
What am I doing wrong?
回答1:
Eclipse needs a dedicated plugin to support Java 15.
This marketplace solution provides Java 15 support for Eclipse 2020-09 (4.17)
