Fail to upgrade from java 19 to 20 using "update maven project" dialog

[eitan-rosenberg]

Hello all,

My installation:

• "Eclipse IDE for Java Developers" (eclipse-java-2023-03-R-win32-x86_64.zip).

• openjdk-20_windows-x64_bin.zip.

I installed Java 20 Support for Eclipse (https://marketplace.eclipse.org/content/java-20-support-eclipse-2023-03-427)

I am using Maven 3.9.1

Now it's time to upgrade some projects.

My usual procedure (from 2019) is to change the relevant POM properties and then alt-f5 to update the project.

Now the project is NOT change and the only option is to change the execution environment to JavaSE-20 manually.

POM properties

alt-f5

Need to change the execution environment to JavaSE-20 manually.

I also noticed that if I run "update maven project" dialog the project goes back to java 19

That one's on me 🤦: https://github.com/eclipse-m2e/m2e-core/blob/master/org.eclipse.m2e.jdt/src/org/eclipse/m2e/jdt/internal/AbstractJavaProjectConfigurator.java#L119

I'll fix it

@fbricon why not calling org.eclipse.jdt.launching.environments.IExecutionEnvironmentsManager.getExecutionEnvironments() instead of using that loop?

[eitan-rosenberg]

Wow....
That was fast !!!
I will watch for new developments
Thanks.

Hi,
How to get the fixed version ?

Update site ?
https://download.eclipse.org/technology/m2e/releases/latest/

[eitan-rosenberg]

Hi,

Thanks.
Nice code !! (remove a lot of hard coding)
What next ?

[fbricon]

Once https://ci.eclipse.org/m2e/job/m2e/job/master/569/ completes successfully, you can try the next snapshot build from https://download.eclipse.org/technology/m2e/snapshots/latest/ (check the update site contains today's bits)

[eitan-rosenberg]

Ok,
I will wait for:

To finish.

[fbricon]

Java 20 support now available from https://download.eclipse.org/technology/m2e/snapshots/latest/

Thank you for your efforts.
Have a nice weekend.
