Re: Errors setting up openjpa projects in Eclipse

How do you "generate" Eclipse projects? "mvn eclipse:eclipse" from 
OpenJPA source root almost ;-) works for me. I manually fix 
openjpa-kernel/target/generated-sources source path after importing 
projects, but everything else seems to be handled properly.

May be the openjpa devs already aware that for module 'openjpa-kernel' 
the generated sources are not added correctly as Eclipse source folders. 
This could be to do with the javacc-maven-plugin.

Cheers,

Rahul

Re: Errors setting up openjpa projects in Eclipse

Hi,

The following snippet in the root pom.xml causes those folders to be 
added as source folders in Eclipse.

[snip from line: 202]
             <resource>
                <directory>${basedir}/../openjpa-project/</directory>
                <includes>
                    <include>NOTICE.txt</include>
                    <include>LICENSE.txt</include>
                    <include>DISCLAIMER.txt</include>
                </includes>
                <targetPath>META-INF</targetPath>
            </resource>
[/snip]

IMHO, as a work around these resources could be setup in a <profile> 
element which could be activated when a release JAR is built :-)

Cheers,

Rahul

This works for me. The only other thing you need to do is define a M2_REPO
classpath variable which points to your maven 2 repository.

It looks like you have openjpa-examples/target/classes/ specified as a
source folder, and openjpa-examples/target/classes/META-INF specified as the
output folder.

Try using these

Source Folders :
    openjpa-examples/src/main/java
    openjpa-examples/src/test/java

Output Folder :
    openjpa-examples/target/classes

This is what maven should set up when you run mvn eclipse:eclipse.
