Right now, I'm writing a small java application by my own, with few maven pom.xml files. I want to make all my maven packages to compile with jdk 1.6, and I can't find a good way to do it without manually setting it on every single POMs - I'm sick of copy-and-pasting
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
in every single pom.xml file I generate.
Is there a simpler way to resolve this issue?
Create a pom-only (<packaging>pom</packaging>
) project that has the compiler settings (and any other default settings) you want. You give treat it like any other project (release it; deploy it to your Maven repo, etc.).
Put a parent
declaration at the top of your pom files:
<parent>
<groupId><!-- parent's group id --></groupId>
<artifactId><!-- parent's artifact id --></artifactId>
<version><!-- parent's version --></version>
</parent>
It doesn't help much if all you want to set is compiler settings. But if you find yourself configuring lots of plugins, reports and dependencies in the same way across project, you can create one parent to rule them all.
BTW - be careful about declaring dependencies
and plugins
in your parent pom file. Usually you'll want to favor dependencyManagement
and pluginManagement
. See the documentation for more details.
