ECF: Compiling for Java version '1.5' is no longer supported.

[jukzi]

Hello again. Trying to setup a platform workspace from scratch with OOmph as described in https://github.com/eclipse-platform/.github/blob/main/CONTRIBUTING.md results in a workspace with many compilation errors. The root cause seems to be

Compiling for Java version '1.5' is no longer supported. Minimal supported version is '1.8'	BaseID.java	/org.eclipse.ecf.identity/src/org/eclipse/ecf/core/identity	line 0	Java Problem

It seems that even JDT can not compile itself anymore
Compiling for Java version '1.2' is no longer supported. Minimal supported version is '1.8' List.java /converterJclMin/src/java/awt line 0 Java Problem

probably related to eclipse-jdt/eclipse.jdt.core#2761

Have you done a pull on the ecf clone?

[merks]

Sorry wrong concern 🙁. Is everything pulled? I’ve not seen this and keep my sdk ide up to date.

[merks]

I guess you meant the subject prefix to be ecj not ecf.

Note that this appears to be project content problems not setup problems so be sure you have the latest content. I can't check until late in the day.

@merks I did clone everything from scratch. So ECF is up to date. As far as i understand ECJ does not compile projects anymore that try to compile for 1.5 but ECF still configured to compile for 1.5 - see https://github.com/search?q=repo%3Aeclipse%2Fecf%20org.eclipse.jdt.core.compiler.compliance%3D1.5&type=code
@iloveeclipse what is the plan for (almost unmaintained) projects that still build for old java versions?

If this missed something

https://github.com/eclipse/ecf/pull/121/files

It would be best to open an ECF issue or pr for it.

It looks like there is major confusion here:

It's all switched to Java 17.

But wait, there's the java compiler settings as well:

Those are not properly updated. So confusing and error prone...

Seems like competing PRs. That was not intentional.
