Re: [m2e-users] Compiler version weirdness

[Fred Bricon <fbricon@xxxxxxxxx>]

David,

starting from version 2.3.2, maven-compiler-plugin defaults to source 1.5. This is the version defined by default in maven 3.0 final, previous versions used source = 1.4. 

In order for m2eclipse to configure java source compiler to 1.5 by default, you need to either lock the maven-compiler-plugin version in your pom (highly advised) :

...
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>

                <version>2.3.2</version>
            </plugin>
         ...
       </plugins>
    </build>

or you can pick an m2eclipse-core plugin based on maven 3.0 (0.12.0 has been staged here [1]). However, due to an incompatibility between core 0.12.0 and current m2e-wtp 0.11.0, you'd better wait for a fix in the next few days before upgrading.

Hi!

I use Eclipse Java EE Helios SR-1
and m2eclipse items:
 - feature 0.10.2
 - subclipse.feature 0.10.0
 - scm.feature 0.10.0
 - wtp.feature 0.11.0.20101024-0955

I created a new maven project and noticed that the Eclipse classpath and compiler versions
are set to 1.4.

This page* says:
the default source setting is 1.5 and the default target setting is 1.

So I wonder why does m2eclipse configure 1.4 in the Eclipse project.
