Bug 778599 (SOA-1072)

Attachment: Added: example.base.build.xml

Link: Added: This issue is related to SOA-864

Examples are no longer built with Ant, the build file in question was removed during the migration to Maven.

Link: Added: This issue is related to SOA-1166

Please review this draft text for the Resolved Issues section of the Release Notes.

https://jira.jboss.org/jira/browse/SOA-1072

    The example.base.build.xml used by jBPM examples has now been removed. It has
    previously caused some problems but is now no longer needed as examples are now being built
    with Maven rather than Ant.

This release note must be fixed - there is no pom.xml that Maven could use. It seems that the examples are now prepared to be used with RHDS but this is just my guess.

Hello Len,

Because Release Note is erroneous (see comment above) and you reported this issue, can you please provide me with more information so that I can rewrite it?


Thanks,


David

In SOA-P 4.3 CP03, ER1 - there is neither a build.xml or pom.xml file to build/run the examples. 

The examples shipped in the distribution are meant to be loaded into Eclipse/RHDS rather than built from the command line. In the source tree the examples are packaged and tested with maven, but the pom file is not intended for distribution to end users. I misunderstood the original issue report.

To answer the question "how do users build/run the samples?" users need Eclipse with the jBPM jPDL Tools installed. 

1. Choose New -> Other -> jBPM 3 Project. Next.
2. Set the project name of your choice.
3. Uncheck Use default location.
4. Browse, then select jbpm/examples/raise (or any other example). Next.
5. If prompted to locate a jBPM runtime, Browse, then select the jbpm directory. Set name to jBPM 3.2.9 (or the actual version). Next.
6. Uncheck Generate simple process definition. Finish.

Now, this used to work, but with the latest plugin version I always get this error: "Resource 'raise/src/main/java' already exists". So, right now, there is no way to build and run the examples :-(

I'm going to tell Koen about this problem, but apart from that, are build scripts needed for end users to build the examples from the command line?

With JBDS, I can build the "raise" example, but it fails to run with the following exception - we need the classpath, etc. settings that would have been in the build.xml files:

pom.xml file from CP01

Attachment: Added: pom.xml

Provided POM files to package and test the examples shipped with the distribution.

I don't know how Alejandro's scenario has ever worked unless the Eclipse people have changed some of the API in the meantime. I have fixed the GPD and now the scenario to create projects from the jBPM examples *should* work. Nevertheless it feels awkward to do it in such a way and it would be good if there is an import wizard to create all the examples in one go. I'll create a JIRA in JBIDE for this.

The patch is committed against trunk of the GPD. I'll commit it to other relevant branches if needed.

The pom.xml file has been added - but it fails to build the examples in the CR2 build.

We have a chicken-egg problem here. Artifact org.jbpm.jbpm3:jbpm:pom:3.2.9 is not in any repository because this is the upcoming jBPM version. I can't deploy version 3.2.9 because, to my knowledge, it has not been accepted yet. We have two choices here:

1. Tag and deploy a candidate release, e.g. 3.2.9.CR1. This was done for 3.2.7 and 3.2.8
2. Employ the snapshot repository

Alternatively, run the jbpm-examples-dist build in a machine where you have installed the jbpm 3.2.9 artifacts.
