Use installed java version in maven repository

It is a simple question, but I didn't find any good solution.

I have created a maven project that is compatible to java8+. I want that, whenever someone builds the project, maven should use the java installed java version.

In other words, I want soneting like:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.7.0</version>
    <configuration>
        <source>${java.version}</source>
        <target>${java.version}</target>
        <compilerVersion>${java.version}</compilerVersion>
    </configuration>
</plugin>

For JAXB I used the following:

<profile>
    <id>java-9+</id>
    <activation>
        <activeByDefault>true</activeByDefault>
    </activation>
    <dependencies>
        <dependency>
            <groupId>javax.xml.bind</groupId>
            <artifactId>jaxb-api</artifactId>
            <version>2.3.0</version>
        </dependency>
    </dependencies>
</profile>
<profile>
    <id>java-8</id>
    <activation>
        <jdk>1.8</jdk>
    </activation>
    <dependencies>
        <!-- add Java 8 dependencies -->
    </dependencies>
</profile>

It needs to work in cli(mvn commands), eclipse and in IntelliJ.

Solution

  • You can activate a profile based on the JDK:

    <profiles>
  <profile>
    <activation>
      <jdk>1.7</jdk>
    </activation>
    ...
  </profile>
</profiles>
