Development environment

• Manually vendor tools.jar from your system Java JDK. This is required because Maven otherwise will not include these dependency classes in the generated .jar.
  • Find the tools.jar in your JDK system path (e.g., $JAVA_HOME/lib/tools.jar).
  • Find the com.sun:tools dependency declaration in pom.xml.
  • Follow the guidelines at https://maven.apache.org/guides/mini/guide-3rd-party-jars-local.html to manually vendor your system tools.jar at the location described in pom.xml.
• You can build from the command line using mvn clean compile assembly:single. The output is called target/java-language-server.jar.
• Run the language server with java -jar target/java-language-server.jar -l INFO
• During development, it is often easier to build and run from the IDE. The preferred IDE is IntelliJ.
