BUILD FAILED /home/vsts/work/1/s/Src/teatro/nbproject/build-impl.xml:257: The Java EE server classpath is not correctly set up - server home directory is missing. Either open the project in the IDE and assign the server or setup the server classpath manually. For example like this: ant -Dj2ee.server.home=<app_server_installation_directory>
