maven exclude plugin in dependency

Question

I'm using the following Maven dependency:-

    <dependency>
        <groupId>com.opencsv</groupId>
        <artifactId>opencsv</artifactId>
        <version>3.1</version>
    </dependency>

The JRE version I'm using is 1.6, but the above dependency seems to use 1.7, assuming from the following in the opencsv's POM.

    <plugin>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.1</version>
        <configuration>
            <source>1.7</source>
            <target>1.7</target>
            <useIncrementalCompilation>true</useIncrementalCompilation>
        </configuration>
    </plugin>

I'm getting a Unsupported major.minor version 51.0 (unable to load class com.opencsv.bean.MappingStrategy).

Is there any way I can force the dependency to use JRE 1.6?

What will happen if you use `1.6` and `1.6`? I think the compiler plugin is able to compile java code vor Java 7 — Reporter, Dec 18 '14 at 13:43

No dice, what is on maven is built with that version.

what you can do, since the permissive Apache 2.0 license, is to download sources, change the compilation level in the root pom, build it and install it in a local maven repository under a version and name of your choosing.

I'd suggest to store it as a local maven repository within the project, instead of using a system dependency, but that's just personal preference.

Yeah, but 2.3 doesn't have the BeanToCSV feature I was looking for. – Kaushik Dec 18 '14 at 14:17
Well then, that restricts the solution to recompile it with different settings – Lorenzo Boccaccia Dec 18 '14 at 14:45
