Maven版本和java版本冲突

Question

I can only use java 1.6 for my project. So maven version also has to be 2.2.1 . Cannot use maven 3.0. But while building I'm getting following error :

 Error resolving version for 'org.apache.maven.plugins:maven-jar-plugin':Plugin requires Maven version 3.0

this is the pom:

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <version>3.0.0</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
</plugin>

what are the version that we can use?

Answer 1

Changes the source and target to 1.6. If your code does not make use of java8 features then it should work just fine. This will generate a jar that is compatible with any java6 codebase.

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <version>3.0.0</version>
                <configuration>
                    <source>1.6</source>
                    <target>1.6</target>
                </configuration>
</plugin>
