Re: [m2e-users] (n00b Alert) why does my project build and execution env

[Fred Bricon <fbricon@xxxxxxxxx>]

What version of m2e are you using? Since m2e 1.1, if you start with no pom.xml and right-click on your eclipse project and Configure...>Convert to Maven..., the generated pom.xml is supposed to contain the maven-compiler-plugin configuration matching your Eclipse JDT settings.

If you already have a pom.xml, then, no settings conversion is done, m2e uses the already existing pom and you must do as Greg said.

This is really a Maven question, not a Maven on Eclipse (M2E) question, and probably better asked on users@xxxxxxxxxxxxxxxx

However, the reason is simply that Maven defaults to JDK 1.5. To change it, you'll want something like the following in your pom.xml ...

<build>

    <plugins>

        <plugin>

            <groupId>org.apache.maven.plugins</groupId>

            <artifactId>maven-compiler-plugin</artifactId>

            <version>3.1</version>

            <configuration>

                <source>1.6</source>

                <target>1.6</target>

            </configuration>

        </plugin>

    </plugins>

</build>

which configures the compiler plugin to use JDK 1.6

Hi,

Sad to say that I am n00b to m2e (and to be fair, maven overall). I
really like the system, but one thing I don't get is when ever I
convert an existing project to a maven one or start a new maven
project the execution is always J2SE-1.5. Does anyone know why this is
occurring.

Ps. The execution used to be JSE 6
