If a custom goal is defined which wants to call the multiproject plugin twice with different value on the maven.multiproject.includes property the goal multiproject:projects-init must be executed twice. Example: <goal name="release-ejb-client"> <!-- dummy call to init the plugin --> <attainGoal name="maven-multiproject-plugin:register"/> <maven:set plugin="maven-multiproject-plugin" property="maven.multiproject.includes" value="${my.ejb.clients}"/> <maven:set plugin="maven-multiproject-plugin" property="goal" value="ejb:deploy-client"/> <attainGoal name="multiproject:goal"/> <!-- call the nultiproject plugin again but with a different list --> <maven:set plugin="maven-multiproject-plugin" property="maven.multiproject.includes" value="${my.ejb.clients.src}"/> <maven:set plugin="maven-multiproject-plugin" property="goal" value="dist:deploy-src"/> <attainGoal name="multiproject:goal"/> </goal> The first list will be used in the second call to the plugin since there is a flag in multiproject:projects-init that prevents the goal being runned twice. What I want to add is the possibillity to force the execution of multiproject:projects-init. For instance like this: <goal name="release-ejb-client"> <!-- dummy call to init the plugin --> <attainGoal name="maven-multiproject-plugin:register"/> <maven:set plugin="maven-multiproject-plugin" property="maven.multiproject.includes" value="${my.ejb.clients}"/> <maven:set plugin="maven-multiproject-plugin" property="goal" value="ejb:deploy-client"/> <attainGoal name="multiproject:goal"/> <!-- call the nultiproject plugin again but with a different list Fist force the multiproject:projects-init to be executed. --> <maven:set plugin="maven-multiproject-plugin" property="mpprojectsInit" value="false"/> <maven:set plugin="maven-multiproject-plugin" property="maven.multiproject.includes" value="${my.ejb.clients.src}"/> <maven:set plugin="maven-multiproject-plugin" property="goal" value="dist:deploy-src"/> <attainGoal name="multiproject:goal"/> </goal> The new multiproject:projects-init will look like this: <goal name="multiproject:projects-init"> <j:if test="${mpprojectsInit == null || mpprojectsInit == false}"> <j:set var="mpprojectsInit" value="true" /> <ant:echo>Gathering project list</ant:echo> <maven:reactor basedir="${maven.multiproject.basedir}" banner="Gathering project list" includes="${maven.multiproject.includes}" excludes="${maven.multiproject.excludes}" postProcessing="true" collectOnly="true" collectionVar="multiprojects" ignoreFailures="${maven.multiproject.ignoreFailures}" /> </j:if> </goal>
