Here is an overview of the issue:
---------------------------------------------------------------------
Key: MPCASTOR-3
Summary: "castor:generate" not working when using J2SDK >= 1.4
Type: Bug
Status: Unassigned
Priority: Minor
Original Estimate: Unknown
Time Spent: Unknown
Remaining: Unknown
Project: maven-castor-plugin
Assignee:
Reporter: David Thexton
Created: Fri, 23 Apr 2004 7:38 PM
Updated: Fri, 23 Apr 2004 7:41 PM
Environment: Windows or Linux, J2SDK 1.5.0-beta1, 1.4.1 or 1.4.2 or 1.4.2_03, Maven
1.0-rc2
Description:
I have some schema files I generate Java classes from using Castor. A snippet from my
maven.xml looks like:
<attainGoal name="castor:prepare-filesystem"/>
<castor:generate
schema="${maven.src.dir}/xsd/adapter.script.xsd"
package="com.piplusplus.messaging.configuration"/>
When I use JDK 1.3.1 it generates the source correctly. When using any of the newer
Java versions I instead get the following obscure error:
java.lang.NoClassDefFoundError: sun/reflect/ConstructorAccessorImpl
I tried adding the "-X" and "-verbose:class" options to track the problem further and
also tried debugging against with the Castor source in my path. I think I began to
make some progress, but subsequently gave up. From memory it was having problems
unmarshalling the "simple types" (or similar) properties file.
After much lost time I found that the problem was avoided by causing the invokation
of the source generator to be done in a forked process.
This can be achieved by pretending to have a Castor properties file by adding the line
"maven.castor.properties.dir=." to the "project.properties" file, which is the
workaround I'm currently using.
I've also added a patch to always fork, rather than only when a Castor properties file
is available.
If "someone" could take a look at what I've done and commit if appropriate I'd be
appreciative. If not, then at least if I save someone's time I'd be happy too. I
like Maven, but it can be difficult to debug certain problems that occur.
