Subject [jira] Commented: (MECLIPSE-165) Ability to exclude filtered resources from eclipse's source directories
Date Sat, 29 Nov 2008 07:38:20 GMT


Connor Barry commented on MECLIPSE-165:

Any updates yet? This is really a crucial fix for anybody using filtered resources, which
is a basic requirement of a lot of projects...

My workaround is to have a shell script that calls the maven goal, and additionally an ant
script that modifies the resulting .classpath file to exclude ALL filtered resources, not
only the **/*.java files. There's two regexes to account for the two possible attribute orders,
which are seemingly random; just a hack, I'm sure there's a better way.

----------------------------- eclipse-config.bat:
@echo off

set _REALPATH=%~dp0

call %M2_HOME%/bin/mvn eclipse:clean eclipse:eclipse
call %ANT_HOME%/bin/ant fix-classpath

----------------------------- build.xml   (add a bogus env target if necessary):

<?xml version="1.0"?>
<project name="xxx" default="env">
<target name="fix-classpath">
		<echo message="Fixing the WTP settings..." />
		<replaceregexp file=".classpath" byline="true">
			<regexp pattern='(.*)excluding="\*\*/\*\.java"(.*)path="src/main/resources-filtered"(.*)'
			<substitution expression='\1excluding="**/*"\2path="src/main/resources-filtered"\3'
		<replaceregexp file=".classpath" byline="true">
			<regexp pattern='(.*)path="src/main/resources-filtered"(.*)excluding="\*\*/\*\.java"(.*)'
			<substitution expression='\1excluding="**/*"\2path="src/main/resources-filtered"\3'

> Resources should be in the classpath from Eclipse's point of view because they end up
being in the classpath from Maven 2's point of view, but whenever resources are marked as
being filtered by M2, Eclipse puts them unfiltered in the classpath thus introducing an inconsistency
between Maven 2 and Eclipse.
> Whether or not to include filtered resource directories in eclipse's sources directories
is therefore a real dilemna. While I'm sure a consistent solution to this dilemna will eventually
be found, it would be great to let the user choose what to do in the meantime.
> The attached patch adresses this issue by adding a parameter, 'excludeFilteredResourcesFromSourceDirs',
which when set to true prevents filtered resource directories from being added to eclipse's
source directories. The parameter defaults to false to avoid changing current projects' behavior.
> Regards,

> PS: This parameter could be overriden on a per resource directory basis as mentionned
in MECLIPSE-162. This is not adressed by the attached patch though
