Reproduce steps:

1. Test project on Mendix 9.18.4
2. Download JWT module from Marketplace (v3.2.2)
3. Download SapAuthentication module (v2.1.9)
4. Run Mendix Userlib Cleaner
5. cleanJars ▶ WARN 00a Would remove file jackson-databind: ..\userlib\jackson-databind-2.14.1.jar (instead of jackson-databind-2.13.4.2.jar)

If the cleaner actually removes this jackson-databind-2.14.1.jar file, the project build will succeed but SapAuthentication fails on runtime with this error:
2023-04-08T08:04:12.323Z [APP/PROC/WEB] OUT CRITICAL - M2EE: An unhandled error occurred in the MxRuntime.
2023-04-08T08:04:12.323Z [APP/PROC/WEB] OUT CRITICAL - M2EE: java.lang.NoClassDefFoundError: com/fasterxml/jackson/core/util/JacksonFeature

• write test case(s)
• included in Actions CI workflow

The Mendix m2ee_log.txt logs the libraries that are overruled.
Which means there is a safe way to clean duplicated libraries using this log as reference/input.

Adding 2 sources.
m2ee_log.txt
m2ee_logx.txt

High level:

• Walk through all java files in the project

• Create list of classes with full names. E.g. org.json.blaat.hello

• Walk through all jars and create list of all classes with full names also

Compute the difference and identify which jars can be removed.

Hi,

It did find the right jars, nice job. I used 1.2.0.

It failed to process these jars in some Mx projects I have access to, probably incompatible manifest formats?

Email_Connector is deleted which is not correct.

Sometimes a metafile is put in the userlib directory to indicate which modules depend on a JAR. For example:

accessors-smart-2.4.7.jar
accessors-smart-2.4.7.jar.MendixSSO.3.0.0
accessors-smart-2.4.7.jar.MendixSSO.RequiredLib
accessors-smart-2.4.7.jar.Required.by.oauth2-oidc-sdk.8.36.2
accessors-smart-2.4.7.jar.Required.by.oauth2-oidc-sdk.9.15

When cleaning the userlib directory, these metafiles are left behind. It would be nice if there was a feature flag that also removed these metafiles.

My project has org.hsqldb.hsqldb-2.5.0.jar and org.hsqldb.hsqldb-2.71.jar in userlib and the duplicate was not detected. I've attached both jars.

The jars are added by the Database Connector module https://marketplace.mendix.com/link/component/2888
