Hello everyone,

I'm feeling like I've gotten way out of my depth here and need some guidance.
I have a very basic question but due to the lack of experience in eclipse developments, this a very hard to figure out alone.

What I am trying to do
Perform a small modification to `eclipse.jdt.core`, rebuilt, and use the locally built jar in my research project.

What steps I have taken so far
1. Created an eclipse workspace as described in Link
2. Built eclipse.jdt.core using the mvn -P build-individual-bundles package
3. Added the resulting jar file (`org.eclipse.jdt.core-3.23.0-SNAPSHOT.jar`) which is created in the target folder to my project as a maven dependency.

Problem
Even though my project successfully compiled with the modified jar file, it gives me the following run time error.

Exception in thread "pool-2-thread-1" java.lang.NoSuchMethodError: org.eclipse.core.runtime.SubMonitor.split(I)Lorg/eclipse/core/runtime/SubMonitor;
	at org.eclipse.jdt.core.dom.ASTParser.createAST(ASTParser.java:820)
	at utils.JavaASTUtil.parseSource(JavaASTUtil.java:87)
	at change.CFile.<init>(CFile.java:32)
	at change.RevisionAnalyzer.buildGitModifiedFiles(RevisionAnalyzer.java:310)
	at change.RevisionAnalyzer.analyzeGit(RevisionAnalyzer.java:130)
	at change.ChangeAnalyzer.analyzeGit(ChangeAnalyzer.java:243)
	at change.ChangeAnalyzer.analyzeGit(ChangeAnalyzer.java:228)
	at main.MainChangeAnalyzer$2.run(MainChangeAnalyzer.java:99)
	at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128)
	at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628)
	at java.base/java.lang.Thread.run(Thread.java:834)


Additional steps
1. When I use the eclipse.jdt.core library in the maven central repository it works perfectly fine. It suggests that the problem is with the locally built jar.
2. I had to use Java 11 when configuring the eclipse workspace. Therefore, I changed Java version of my project to 11.


Questions
Is there any configuration or any setting that I need to use in eclipse core runtime when using locally built jar?
Any idea to Investigate this error is much appreciated.

pom.xml of my project is as below.

After experimenting with couple of versions of org.eclipse..runtime, I could successfully run my project with the locally built JDT Core. However I have no idea for the existence of couple of maven repositories for org.eclipse.core.runtime.

I removed below dependency
        <dependency>
            <groupId>org.eclipse.core</groupId>
            <artifactId>runtime</artifactId>
            <version>3.10.0-v20140318-2214</version>
        </dependency>

I added below dependency.
		<dependency>
			<groupId>org.eclipse.birt.runtime</groupId>
			<artifactId>org.eclipse.birt.runtime</artifactId>
			<version>4.6.0-20160607</version>
		</dependency>


I would be grateful to you, If somebody can explain the reason for maintaining multiple maven repositories for `org.eclipse.core`. Thank you.
