maven multimodule project, override parent version -

borrowing example similar question, have 2 projects: parent project: a, sub project: b

in a/pom.xml:

<groupid>com.dummy.bla</groupid> <artifactid>parent</artifactid> <version>2.0</version> <packaging>pom</packaging> 

in b/pom.xml, have:

<parent>     <groupid>com.dummy.bla</groupid>     <artifactid>parent</artifactid>     <version>2.0</version>      </parent>  <groupid>com.dummy.bla.sub</groupid> <artifactid>kid</artifactid> 

i run tests on b follows,

mvn test -pl b 

is possible override parent version, following?

mvn test -pl b -dparent=1.0 

you parent project version have dynamic using maven property can override system one.

all child modules have inherit parent version , should not define theirs or process down broken.

update parent poject descriptor below:

<project>   <modelversion>4.0.0</modelversion>    <groupid>com.dummy.bla</groupid>   <artifactid>parent</artifactid>   <version>${project.custom.version}</version> <!-- dynamic project version defaults 2.0 -->   <packaging>pom</packaging>    <name>parent</name>    <properties>     <project.custom.version>2.0</project.custom.version>   </properties>    <modules>     <module>kid</module>   </modules>   <!-- ... --> </project> 

then declare parent poject in submodules using same dynamic version:

<project>   <modelversion>4.0.0</modelversion>   <parent>     <groupid>com.dummy.bla</groupid>     <artifactid>parent</artifactid>     <version>${project.custom.version}</version>   </parent>   <artifactid>kid</artifactid>   <name>kid</name>   <!-- ... --> </project> 

the command line invocation trick using either version declare or default one:

~ cd parent/ ~ mvn -pl kid -dproject.custom.version=3.1
