The following result is from the second step of the build process of the wiki

[INFO] importer-attributes-ear ............................ SUCCESS [  0.475 s]
[INFO] ------------------------------------------------------------------------

[INFO] ------------------------------------------------------------------------
[INFO] Total time:  28:09 min
[INFO] Finished at: 2019-04-10T16:53:04+08:00

However, when go to the deploy step, it shows

An error has occurred Error occurred during deployment: Exception while preparing the app : Invalid resource : jdbc/docdokuPUpm. Please see server.log for more details. Exception while invoking class org.glassfish.persistence.jpa.JPADeployer prepare method : java.lang.RuntimeException: Invalid resource : jdbc/docdokuPUpm Invalid resource : jdbc/docdokuPUpm Exception while invoking class org.glassfish.persistence.jpa.JPADeployer prepare method : java.lang.RuntimeException: Invalid resource : jdbc/docdokuPUpm Invalid resource : jdbc/docdokuPU__pm

Have no clue how to fix it.

Working on Ubuntu 18.04 x86_64
