commit 98bfafd1485574d849c24a22158f407578840d0e
Author: Samuel Trégouët <[hidden email]>
AuthorDate: Sat Dec 7 14:47:34 2019 +0100

    Improved: Resolve classpath conflict on `freemarkerTransforms.properties`
    (OFBIZ-11161)
   
    All files in {compoment}/config directories are placed in jar
    root (cf. sourceSets definition in build.gradle) but there are 4 different
    `freemarkerTransforms.properties` in ofbiz (content, product, webapp, widget).
    This works fine because we are adding config directories in classpath (through
    classpath tag in ofbiz-component.xml), but this is not really intuitive. So to
    make things clearer this patch move `freemarkerTransforms.properties` into
    `src/main/resources` with a namespace package and `FreeMarkerWorker.java` is
    modified accordingly.

    Improved: Do not add classpath info to the classloader classpath (OFBIZ-11161)
   
    Those directories are already added in the classpath by the build
    system. The classpath info defined in “ofbiz-component.xml” files are
    now only used to retrieve label files.
