#12 Compatibility with Maven 3?

[Frank Puechl]

Hi,

maybe I am wrong here, but I have a problem running pldoc with maven 3's "mvn site". I receive the following error and I am not sure what causes the error. Maybe it is because of Maven 3.

Thanks in advance,
Frank

Works under maven 3.0.3 - pldoc.sourceforge.net is created using the site plugin

[Frank Puechl]

So maybe the problem is not related to Maven 3?

Any idea?

[Stuart Turton]

Try refreshing the source code; the project description (pldoc/trunk/pom.xml) has changed quite a lot since March.

Secondly, there has been a few releases since March: if you just want to run pldoc, you can download one of the bundles and run it without having to compile the source code.

if you _DO_ compile it, be aware that it now takes _MUCH_ longer to compile.

But it does cope with more source code.

Good luck and please add a comment to says whether or not the problem still exists.

Summary

Check source code out of Subversion repository
svn checkout https://pldoc.svn.sourceforge.net/svnroot/pldoc/pldoc/tags/pldoc-0.9.4 pldoc

Compile and package the code
mvn -U package

cd test
./pldoc_test.bat to ./pldoc_test.sh

Great, release 2.3 works properly for me.

Thanks to Stuart.

Many years later I had the same issue:
Solution : Add a dummy jdbc link
e.g.

<plugin>
                <groupId>net.sourceforge.pldoc</groupId>
                <artifactId>maven-pldoc-plugin</artifactId>
                <version>3.0.20</version>
                <configuration>
                    <dbUrl>jdbc:dummy.host:1234/dummy</dbUrl>
                </configuration>
</plugin>
