I am developing a desktop application based on Eclipse Kepler plugins. Initially, I used Kepler 4.3.2 (2014) with JDK 1.8.0_231. Later, I use Kepler 4.33 (2024)and JDK 17. During this upgrade, I encountered a plugin version conflict.

Kepler 4.33 uses com.ibm.icu_76.1.0.jar, while the old version relied on com.ibm.icu_50.1.1.v201304230130.jar. These two versions are incompatible.

If I replace com.ibm.icu_50.1.1.v201304230130 with com.ibm.icu_76.1.0, the application can run in Eclipse. However, I face an error when setting the target platform: Problems occurred while resolving the target contents: File does not exist: ... com.ibm.icu_50.1.1.v201304230130.

File does not exist: ....metadata.plugins\org.eclipse.pde.core.bundle_pool\plugins\com.ibm.icu_50.1.1.v201304230130.jar.

If I replace com.ibm.icu_76.1.0 with com.ibm.icu_50.1.1.v201304230130, the IDE(Kepler 2024) cannot started.

On the other hand, if I do not replace com.ibm.icu_50.1.1.v201304230130 with com.ibm.icu_76.1.0, I cannot add the required plugins, and the application fails to run because there are 2 versions of com.ibm.icu.

Here is the CAR.target file:

After updating the CAR.target file by changing the repository path and version of units:

    There is no such thing as "Kepler 2024" release. Eclipse Kepler was the name of the 4.3 release of the Eclipse IDE from 2013/4. There are 4 releases of the Eclipse IDE in 2024 called 2024-03, 2024-06, 2024-09 and 2024-12. From the icu version it seems that you are using Eclipse 2024-12 (4.34) Commented Dec 19, 2024 at 7:53

    It sounds like you need to update your target platform to specifiy the new version of icu Commented Dec 19, 2024 at 7:58
  • Thank you for your suggestion! However, how can I update the target platform properly? I’ve removed com.ibm.icu_50.1.1.v201304230130.jar from all locations and replaced it with the new version. Despite this, when I reload the target platform, I still encounter the error: File does not exist: ... com.ibm.icu_50.1.1.v201304230130. Commented Dec 19, 2024 at 15:46
  • Are there conflicts with other related plugins? Should I identify and update them as well? Commented Dec 19, 2024 at 15:51

    Please include your target platform definition file in your question. Your question still tells "I upgraded to Kepler 2024", but as already said by greg-449, Eclipse Kepler was the name of the Eclipse simultaneous release more than ten years ago. Nowadays, the simultaneous releases are named with a date of the year and month of the release: en.wikipedia.org/wiki/Eclipse_(software)#Releases It is unclear from where to where you upgraded and which error message you get exactly for which action.
