Hi, I downloaded the solr source from https://github.com/apache/lucene-solr and checked out to branch_7_7
Configured intellij using the steps on https://cwiki.apache.org/confluence/display/LUCENE/HowtoConfigureIntelliJ. Configured the project SDK too as mentioned. Facing the following problems - Unable to navigate from one class to another. "Find usages" of any public method doesn't return any result. Unable to open any class by searching for it. Have to navigate in the project structure to open any class - Not getting the Run/Debug option on any test case - Executing any pre configured test configuration fails with the single error "Error Running <configuration>. No junit.jar". Have added junit in Project Structure -> Modules I also tried setting it up via maven using steps in https://github.com/apache/lucene-solr/blob/branch_7_7/dev-tools/maven/README.maven - ant generate-maven-artifacts - ant get-maven-poms - cd maven-build - mvn install -DskipTests I don't think I can execute test cases from inside the maven-build folder as they are all inside the target of their respective modules. There are dependency errors in intelliJ if i open either the root folder (lucene-solr) or the sub folder maven-build in IntelliJ Root folder - "Package name org.apache.solr.ltr does not correspond to file path test.org.apache.solr.ltr" maven-build folder - Facing same issue as with ant and unable to navigate / find usages. Getting the Run option but Run configuration is broken as it says "Class org.apache.solr.ltr.feature.TestEdisMaxSolrFeature not found in module solr-ltr" What am I doing wrong and how do I run test cases like TestEdisMaxSolrFeature on IntelliJ ?
