1) Compiling the examples on a machine where jBPM 3.2.5 has been built does not show the problem. Presumably, the parent POM is already cached locally (~/.m2). 2) Compiling the examples on a fresh machine shows maven trying to fetch the parent POM and failing: [INFO] Scanning for projects... Downloading: http://repo1.maven.org/maven2/org/jbpm/jbpm3/jbpm/3.2.5.SP1/jbpm-3.2.5.SP1.pom [INFO] ------------------------------------------------------------------------ [ERROR] FATAL ERROR [INFO] ------------------------------------------------------------------------ [INFO] Failed to resolve artifact. GroupId: org.jbpm.jbpm3 ArtifactId: jbpm Version: 3.2.5.SP1 Reason: Unable to download the artifact from any repository org.jbpm.jbpm3:jbpm:pom:3.2.5.SP1 from the specified remote repositories: central (http://repo1.maven.org/maven2) So, it looks like we need to make the jBPM 3.2.5 SP1 POM available somewhere.
You need to run > mvn install This copies the maven output artefacts to your local repo
Any mvn command line (install, compile) will produce the error, as we have nowhere to fetch the output artifacts from. In the jBPM installation, we have the examples directory, which includes the POM, but none of the other parts of the source, nor any hints as to where to get the jBPM artifacts. So, maven looks for the artifacts in the default repository (repo1.maven.org). For users who install jBPM, there needs to be some way to build the examples. Even better, a way to build the examples with no Internet connection, i.e., we ship everything that they need.
Link: Added: This issue depends JBPM-2050
The examples can now be compiled, as repository.jboss.org is looked at for the main artifact. When we build the next CR, we will need to upload the jBPM main artifact to the repository. It will not be possible to build the examples without first downloading the artifact to the local repository (~/.m2).
From Alejandro Guizar in SOA-647: jBPM 3.2.5.SP4 is tagged and published to the maven repo (See also JBPM-2112)
