java - Maven assembly descriptor properties -


i want pack 2 or more similar distributions, difference path data set inside distributions.

given example path: ${project.basedir}/src/config/dataset1

<?xml version="1.0" encoding="utf-8"?> <assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2"           xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"           xsi:schemalocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2 http://maven.apache.org/xsd/assembly-1.1.2.xsd">      <id>dataset1</id>     <formats>         <format>zip</format>     </formats>      <filesets>         <fileset>             <directory>${project.basedir}/src/config/dataset1/aaa</directory>             <outputdirectory>conf/aaa</outputdirectory>         </fileset>         <fileset>             <directory>${project.basedir}/src/config/dataset1/bbb</directory>             <outputdirectory>conf/bbb</outputdirectory>         </fileset>     </filesets>      <!-- many more filesets... -->  </assembly>

now want same assembly descriptor different data set, example: ${project.basedir}/src/config/dataset2

off course create 2 assembly descriptors. again have keep in mind change multiple places when needed, or worse when adding dataset or two.

is there way how solve this, creating multiple executions , passing properties it? or ever nicer?

thanks

edit: wish item solve everything: https://jira.codehaus.org/browse/massembly-445

yes, use properties this.

  1. create properties (with default value) parts differs between executions in pom.xml. e.g.:
<properties>     <dataset.dir>config/dataset</dataset.dir> </properties>

  1. use them in assembly descriptor other property (e.g ${project.basedir} )

  2. for different executions could:

    • use several build profiles (maven profiles) override property value;

    • or pass values directly mvn call argument (like mvn package -dprop=val)

also, if want use these properties in other place, populate them via placeholders in config using other maven plugins (for instance, maven-resource-plugin).
