Issue

  • When leveraging Liferay Developer Studio / IDE to build Liferay 2025.Q1.3, my build fails with indications that Tomcat is not able to download
  • Example error:
  • Execution failed for task ':modules:demo-local-service-wrapper-test:setUpTestableTomcat'.

    > Can't get http://archive.apache.org/dist/tomcat/tomcat-9/v9.0.90/bin/apache-tomcat-9.0.90.zip to <DESTINATION>

 

Environment

  • Liferay 2025.Q1.3
  • Liferay Developer Studio / IDE version 3.10.3

 

Resolution

  • The download of the Tomcat 9 zip file is necessary, because the Tomcat Manager is required by Arquillian, however it is not part of the default Liferay bundle.

  • During the setUpTestableTomcat task (which is part of the testIntegration task) the Tomcat zip is downloaded and the Tomcat Manager is copied from it to the Liferay bundle’s Tomcat installation.

  • To resolve, make sure your network has access to download external files.

  • Alternatively, you can download the Tomcat zip and copy the webapps/manager folder to the {liferay_home}/tomcat/webapps folder manually. This will solve the issue as the setUpTestableTomcat task checks if the webapps/managerfolder is present, and if not, it will go through the download/copy process.

 

Additional Information

  • For Liferay 2025.Q1.0-lts and onwards, you will need to leverage Liferay Developer Studio / IDE version 3.10.3 
    • LPD-49776 - Cannot Start 2025.Q1-lts bundle from Developer Studio 3.10.2
    • LPD-49691 - Release Liferay IDE v3.10.3
