Debugging a Gradle project with Eclipse

Install Gradle

You will need to have gradle installed.

Setting up gradle debug configuration for all projects

• Add this init.gradle file in your $HOME/.gradle directory:

  allprojects {
      tasks.withType(Test) {
          if (System.getProperty('DEBUG', 'false') == 'true') {
              jvmArgs '-Xdebug',
                  '-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=9009'
          }
      }
  
      tasks.withType(JavaExec) {
          if (System.getProperty('DEBUG', 'false') == 'true') {
              jvmArgs '-Xdebug',
                  '-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=9009'
          }
      }
  }

• Import the gradle project in Eclipse. You may use plugins like Gradle STS or Buildship.

Create a new Remote Java Application configuration.

• Open Eclipse and go to Run -> Debug Configurations....
• Select the Remote Java Application in the list of configuration types on the left.
• Click the New toolbar button. A new remote launch configuration is created and three tabs are shown: Connect, Source, and Common.
• In the Project field of the Connect tab, type or browse to select the project to use as a reference for the launch (for source lookup).
• In the Host field of the Connect tab, type the IP address or domain name of the host where the Java program is running. If the program is running on the same machine as the workbench, type localhost.
• In the Port field of the Connect tab, type the port where the remote VM is accepting connections. In our case the port will be 9009.
• Click Apply.

Enable gradle Debug

• For test task debugging run $ gradle -DDEBUG=true test in the terminal.
• For run task debugging run $ gradle -DDEBUG=true run in the terminal.

Now you can use your Eclipse debugger to debug an ATMOSPHERE project.
