My JUnit tests executes with maven build in Java 11, but unable to run same Junit tests via RunIT->Run As->Units, which always says not JUnits found

Question

My module test project is supposed to be built using Java 11 as it is referencing to a jar which is build in Java 11. Hence I had to compile my code in Java 11. When I do Maven clean install, my JUnit test cases are executed without any issue. But when I tried to run my test cases via RunIT->Run As-> JUnit tests, it says "no JUnit tests found"

• When I first set up this project, I was able to run via RunIT->Run As-> JUnit tests, which worked absolutely fine. But I had another module in my workspace, which was working on Java 1.8. After testing the tests in that module and coming back to my test project, this stopped working.
• When I set compiler to Java 1.8, my tests are identified

• Following are the configurations I have tried with

  • I am working on Eclipse Java 2019-03, which supports Java 11
  • I have set Preferences-> java -> Compiler -> Compiler compliance level to 11, and Installed JREs point to Java 11.
  • Project -> Properties -> Java Build Path -> Libraries -> set to Java 11
  • Project -> Properties -> Java Compiler -> set to Java 11
  • In my module pom, I am referencing to JUnit 4
  • While executing RunIT-> Run As -> Run Configurations, I have selected Java 11 JRE.
  • I have done maven clean install, and all the test-classes are present in the expected target folder. I have Maven-> clean, deletes the target folder.
  • After building my project via Maven, I have done "Maven Update" as well.

• In my module pom file, I have set compiler version

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>${maven-compiler-plugin.version}</version>
        <configuration>
        <source>11</source>
        <target>11</target>
        <encoding>${project.build.sourceEncoding}</encoding>
        <testSource>11</testSource>
        <testTarget>11</testTarget>
        </configuration>
</plugin>

The issue got solved by opening the Java 11 project in different workspace. Before that I ensure that JAVA_HOME is set with to JAVA 11 and then open the eclipse.
