Errors setting up openjpa projects in Eclipse

[Rahul Thakur]

Hi,

I am just starting out with OpenJPA and tried generating and importing 
projects in an Eclipse workspace but I get to see the following errors 
for all the imported modules.


[snip - as copied from Problems view]

Severity and Description Path Resource Location Creation Time Id
Cannot nest output folder 'openjpa-examples/target/classes/META-INF' 
inside output folder 'openjpa-examples/target/classes'  openjpa-examples 
Build path 1168072979859 63185


[/snip]

Thanks in advance,

Rahul

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.

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.

Hi,

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


[snip from line: 202]

   ${basedir}/../openjpa-project/
   
   NOTICE.txt
   LICENSE.txt
   DISCLAIMER.txt
   
   META-INF
   
[/snip]

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


Cheers,

Rahul

Re: Errors setting up openjpa projects in Eclipse

[Rahul Thakur]

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.

Rahul

Missing ProductDerivation resource error

[Rahul Thakur]

Hi,

I am trying to create an OpenJPA Maven2 plugin that runs to the 
PCEnchancer to start with, but when I attempt to run it I get an error 
complaining about missing resource ProductDerivation (attached below). 
The message indicates that it should have been installed as a part of 
the openjpa distribution which I installed into my local m2 repo from 
instructions in docs on openjpa site.


Do I need to explicitly specify one or am I missing something here?

TIA,

Rahul
