Help building Eclipse from scratch

[mbazley2]

I'm trying to follow the instructions here to build from master on MacOS: https://github.com/eclipse-platform/eclipse.platform.releng.aggregator/wiki/Platform-Build

I had to skip running the tests as 3 of them failed. I don't know if this is a known problem or not.

My next problem is that, although the mvn clean verify -DskipTests=true step claims to have completed successfully, I cannot find where it might have put its results. The linked page claims:

Packaged SDK zip files are located in your eclipse.platform.releng.aggregator directory under

org.eclipse.releng.tychoeclipsebuilder/sdk/target/products/

But there is no directory org.eclipse.releng.tychoeclipsebuilder in my eclipse.platform.releng.aggregator checkout directory. There is a similarly named directory, eclipse.platform.releng.tychoeclipsebuilder, but it does not contain an sdk subdirectory. I tried running find in the checkout but it failed to locate either the aforementioned directory or the other one mentioned in the document, org.eclipse.repository.

Does anyone have any recent experience building Eclipse who can suggest a way forward?

The *.product files are here so I would expect the target folder to contain the important stuff.

https://github.com/eclipse-platform/eclipse.platform.releng.aggregator/tree/master/eclipse.platform.releng.tychoeclipsebuilder/eclipse.platform.repository

Do a find for things like content.jar, content.xml, *.dmg, *.zip and stuff like that...

Exactly, the compressed products are in the folder eclipse.platform.releng.tychoeclipsebuilder/eclipse.platform.repository/target/products within your eclipse.platform.releng.aggregator clone.
The eclipse update p2-repository is located in the sibling folder, just in case you need it:eclipse.platform.releng.tychoeclipsebuilder/eclipse.platform.repository/target/repository

Looks like this page is quite outdated (probably migrated from the old Eclipse-hosted wiki). I'll try to have a look at it to bring it up-to-date and clean it up.

In general you can have a look at how the projects are build in the eclipse.releng.aggregator repo at:
https://github.com/eclipse-platform/eclipse.platform.releng.aggregator/blob/a3f892d4323d16cd9d9f815aeb0dab9cd5e6896a/Jenkinsfile

Of course this does a bit more, but it should give an impression what's actually necessary in terms of tools (JDK-21, maven-3.9, of course git, ...).

The tests are often a bit sensitive, so it's not surprising that some fail on a local machine. But some even fail on the build-server as you can see when you look at the test-results of the respective build at:
https://download.eclipse.org/eclipse/downloads/

Furthermore running the tests takes quite some time. For the fastest local build you should probably run the build also in parallel:
mvn clean verify -DskipTests=true -T 1C

Then you can get it completed in about 20min, depending on your machine.
