18.10.08 16:10:51 CEST: Error on adding indexing context central; read past EOF
18.10.08 16:10:51 CEST: Eclipse is running in a JRE, but a JDK is required
Some Maven plugins may not work when importing projects or updating source folders.

thank YOU

I suggest you'd quit Eclipse, set up external environments (if applicable) and
start Eclipse again using: "eclipse -clean" (using a command line interpreter
or shell).

kind regards,
