I just created a plugin directory at https://svn.apache.org/repos/asf/manifoldcf/integration/solr-8.x/trunk . Code committed there builds but it doesn't test properly because of the following exception:
>>>>>> [ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.18.1:test (default-test) on project apache-manifoldcf-solr-8.x-plugin: Execution default-test of goal org.apache.maven.plugins:maven-surefire-plugin:2.18.1:test failed: There was an error in the forked process [ERROR] org.apache.maven.surefire.util.SurefireReflectionException: java.lang.ClassNotFoundException: org.apache.maven.surefire.junit4.JUnit4Provider [ERROR] at org.apache.maven.surefire.util.ReflectionUtils.loadClass(ReflectionUtils.java:252) [ERROR] at org.apache.maven.surefire.util.ReflectionUtils.instantiateOneArg(ReflectionUtils.java:128) [ERROR] at org.apache.maven.surefire.booter.ForkedBooter.createProviderInCurrentClassloader(ForkedBooter.java:230) [ERROR] at org.apache.maven.surefire.booter.ForkedBooter.invokeProviderInSameClassLoader(ForkedBooter.java:199) [ERROR] at org.apache.maven.surefire.booter.ForkedBooter.runSuitesInProcess(ForkedBooter.java:155) [ERROR] at org.apache.maven.surefire.booter.ForkedBooter.main(ForkedBooter.java:103) [ERROR] Caused by: java.lang.ClassNotFoundException: org.apache.maven.surefire.junit4.JUnit4Provider [ERROR] at java.net.URLClassLoader.findClass(URLClassLoader.java:381) [ERROR] at java.lang.ClassLoader.loadClass(ClassLoader.java:424) [ERROR] at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:349) [ERROR] at java.lang.ClassLoader.loadClass(ClassLoader.java:357) [ERROR] at org.apache.maven.surefire.util.ReflectionUtils.loadClass(ReflectionUtils.java:244) [ERROR] ... 5 more [ERROR] <<<<<< This is odd because the plugin depends on solr and solr has a transitive maven dependency on junit. I'll see if a direct dependency works...
