[jboss-jira] [JBoss JIRA] (DROOLS-1394) Use Maven for compiling the workbench projects

[Toni Rikkola (JIRA)]

Toni Rikkola commented on DROOLS-1394:
--------------------------------------

Some additional information about this ticket. We already had the possibility to do any Maven build in the guvnor webapp. Now that the webapp has been removed the code is most likely gone, but should exist in git history. 

How this used to work, was it dumped the git repo to the server hard drive and fired Maven. Maven had to be installed for this to work.

The issues with this approach:
* Code is duplicated to two locations
* Anyone who has access to the server can see the source code
* Harder setup, since you need to install Maven

I imagine there is a better way.

> We currently use the kie-maven-plugin internally to compile the kjar's and only use Maven to provide the information about parent projects and dependencies for the project.
> Yet we have the power of Maven underneath and we do not use it. It is impossible to use simple features like ignoring folders or moving code. Or more complicated, for example if you have your own rule asset format and need a Maven plugin to generate the DRL out of it.
> However it is possible to set this functionality up. This causes problems:
> * Same git tag built in the workbench produce different results depending on the Workbench version that is being used. This means that if you want to rebuild a lost kjar, you need to install the same workbench version that was originally used to create the first one
> * Projects build in command line/build server can produce different kjars than the ones built with the workbench
