Errors deploying plugin [message #1857500]

Good morning,

Running Eclipse 2022-12, Java 17 and IBM Semeru MAT 1.13.0 versions

Developed a commandLine based plugin to query and report on various heapdump and coredump objects. The project works deploying into MAT in GUI mode. The project successfully executes several queries creating output files.

The commandLine version encounters an error when trying to deploy the commandLine's plugin project into MAT. Here's the error:
Cannot complete the install because one or more required items could not be found.
Software being installed: MAT_CommandLineParserFeature 1.0.0.202302091058 (MAT_CommandLineParserFeature.feature.group 1.0.0.202302091058)
Missing requirement: MAT_CommandLineParser 1.0.0.202302091058 (MAT_CommandLineParser 1.0.0.202302091058) requires 'osgi.ee; (&(osgi.ee=JavaSE)(version=17))' but it could not be found
Cannot satisfy dependency:
From: MAT_CommandLineParserFeature 1.0.0.202302091058 (MAT_CommandLineParserFeature.feature.group 1.0.0.202302091058)
To: org.eclipse.equinox.p2.iu; MAT_CommandLineParser [1.0.0.202302091058,1.0.0.202302091058]

Any suggestions? I've included the following in the MANIFEST.MF file based on the error and no help. The entry's:
Bundle-RequiredExecutionEnvironment: JavaSE-17
Require-Capability: osgi.ee; (&(osgi.ee=JavaSE)(version=17))

Thanks,
Rich Olson

Here are some things to try:

Are you sure you are running with Java 17 for the command line version of MAT?
Does it work with osgi.ee; (&(osgi.ee=JavaSE)(version=11)) ?
Does this look relevant? https://www.eclipse.org/forums/index.php/t/1110558/ and https://www.eclipse.org/forums/index.php?t=msg&th=1110558&goto=1851646&#msg_1851646 where 'The runtime shipped by efxclipse does not know Java-17.' which might be similar to the situation with MAT 1.13.0.
MAT 1.13.0 is based on Eclipse 2022-03 which might not know about Java 17. Does it work with a snapshot build as MAT 1.14.0 will be based on Eclipse 2022-12, which requires Java 17.
