how to build JPF(pageflows) in Maven2
Hi, all,
I have a problem when building beehive page flows in Maven2, I
couldn't find the build-pageflows plugin on ibiblio site for Maven2, So
I compile those JPF files using below snippet:
<build>
<plugins>
...
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<phase>compile</phase>
<configuration>
<tasks>
<echo>ant compile beehive pageflows
${beehive.dir}</echo>
<import
file="${beehive.dir}/apache-beehive-incubating-1.0m1/ant/beehive-tools.x
ml"/>
<build-pageflows
srcdir="src/java"
classpathref="maven.dependency.classpath"
webcontentdir="${basedir}"
tempdir="target/temp">
</build-pageflows>
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
<plugins>
<build>
But it gave such error message:
[INFO] [antrun:run {execution: default}]
[INFO] Executing tasks
[echo] ant compile beehive pageflows
D:/WLS_WORK/subv/src_load10/beehive

Why? (the ant script can be run successfully using ant command)
Please help,

Re: how to build JPF(pageflows) in Maven2
Posted by Wayne Fay <wa...@gmail.com>.
I've had some good luck running certain things in Antrun, and then bad
luck with many other things.
I'd guess that your JPF dependencies (the Ant plugins that enable the
JPF functionality themselves) are not being registered/discovered in
Maven/Antrun as they are in native Ant. Take a look at where the NPE
is getting thrown:
> Caused by: java.lang.NullPointerException
> at
> org.apache.tools.ant.taskdefs.ImportTask.execute(ImportTask.java:96)
> at
> org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:275)
> at org.apache.tools.ant.Task.perform(Task.java:364)
To me, this can be loosely translated as "Ant was attempting to
PERFORM the TASK you gave it (JPF) and was unable to EXECUTE the
IMPORT TASK command due to an UNKNOWN ELEMENT (the JPF code itself)".
I'd suspect that the JPF jar file needs to be made available to the
Antrun somehow, perhaps as a dependency in your Pom? Not sure about
specifics here.
Ultimately, things are easiest if all your plugins are native Maven2
plugins. Perhaps its a better use of your time to just port the JPF
Ant task to Maven2? :-)

If you look closely at the stack trace you'll see that the source
exception is NullPointerException and that it comes from Ant. So you
need to look for what cause the exception first if you want any help.
