---------------------------------
Fix Version/s: (was: 2.2)
2.2-beta-5
> Property Expansion/Filtering does not always work for System.properties
> -----------------------------------------------------------------------
>
> Key: MASSEMBLY-167
> URL: http://jira.codehaus.org/browse/MASSEMBLY-167
> Project: Maven 2.x Assembly Plugin
> Issue Type: Bug
> Affects Versions: 2.2
> Environment: JDK 1.5.0_10, Maven 2.1-SNAPSHOT, Linux 2.6.18
> Reporter: Daniel Krisher
> Priority: Minor
> Fix For: 2.2-beta-5
>
>
> When using filtering for a file element in an assembly descriptor, System
> properties (e.g. java.version) are not always available (and do not get
> replaced in the filtered file).
> For example, my assembly descriptor contains:
> {noformat}
> <file>
> <source>src/main/files/config/splash.xml</source>
> <outputDirectory>/config</outputDirectory>
> <filtered>true</filtered>
> </file>
> {noformat}
> and splash.xml (pre-filtering):
> {noformat}
> <properties>
> <entry key="title">${project.name}</entry>
> <entry key="Version">${project.version}</entry>
> <entry key="Compiled with Java ">${java.version}</entry>
> </properties>
> {noformat}
> Which results in a post-filtered splash.xml:
> {noformat}
> <properties>
> <entry key="title">ACES Viewer</entry>
> <entry key="Version">0.7-SNAPSHOT</entry>
> <entry key="Compiled with Java ">${java.version}</entry>
> </properties>
> {noformat}
> The problem appears to be in the 'initializeFiltering()' method of the
> FileFormatter class. The filter properties are initialized using:
> filterProperties = new Properties(System.getProperties());
> Changing this to:
> filterProperties = new Properties();
> filterProperties.putAll(System.getProperties());
> Seems to fix the problem.
> The Properties javadocs are a little vague on the constructor parameter:
> public Properties(Properties defaults)
> Creates an empty property list with the specified defaults.
