Use specific versions in setup file

[karypid]

Hello,

I have my IDE setup here on github and every so often I add a version, latest being the 2024-12 version.

Now, I've noticed that if I build the same version twice, it does not produce the same output: newer versions of plugins are picked up as they are released... I was wondering if you have any suggestions on how to prevent this from happening. Is it possible to "freeze" specific versions of features so that even if you run the oomph setup a few months later you get the same output?

You can control what version is installed either by controlling what's visible, i.e, the available update sites, or via version range constraints on the requirements.

You appear to be using "moving target" repository so you'll need to revisit that for sure:

      <repository
          url="https://eclipse-pmd.acanda.ch/release/latest"/>
      <repository
          url="https://github.com/tesla/m2eclipse-tycho/releases/download/latest/"/>

E.g., here we control the range to ensure that the expected version is installed though the upper bound is very loose. We also ensure that repositories that satisfy the constraints are available:

So then, to achieve this one must:

1. Target paths in the repository URLs that match a specific version
2. Specify version limitations

May I ask where the example you got the screenshot from is published? (I suppose there are setup files somewhere on github).

I've been defining a 2025-03 version, carefully selecting the update sites and setting version numbers. It appears however that some projects have practices that make it impossible to properly define versions.

For example, the PMD plugin defines a "latest" version and specific versions for older JDKs. Interestingly:

• To get 4.x you must use "latest" at https://eclipse-pmd.acanda.ch/release/latest
• The current version is 4.6.x **I would like to select this version for "my eclipse 2025-03" that I am defining
• You can get version 4.5.x at update site https://eclipse-pmd.acanda.ch/release/4.5
• You can get version 4.4.x at update site https://eclipse-pmd.acanda.ch/release/4.4
• There is no way to get version 4.6.x as it is only available on "latest" - there is no https://eclipse-pmd.acanda.ch/release/4.6

I have two options:

1. Use "latest" and apply a version filter to [0.0.0, 4.7.0) - this will stop working when 4.7.x is released and latest no longer has a 4.6 version.
2. Use "4.6" alongside "latest" (two repos) alongside the same version filter [0.0.0, 4.7.0) - I would then hope that in the future they will add https://eclipse-pmd.acanda.ch/release/4.6 when 4.7 gets released and the filter will ensure that running oomph in the future picks the (as of now non-existent) future update site and use 4.6.x.

EDIT: In fact, (2) fails because the update site https://eclipse-pmd.acanda.ch/release/4.6 is non-existent
EDIT 2: Raised eclipse-pmd/eclipse-pmd#314 with that project

Any advice how to handle this?
