That's why we suggest locking down your plugin versions in your poms.
Then you'll have controll over which ones you get as snapshots.

The eclipse plugin does not seem to be one that has a default in the
super pom.

Hi, I just enabled all snapshots for plugins, and a side effect of
this was to pull down
org.apache.maven.plugins:maven-eclipse-plugin:2.7-SNAPSHOT version of
eclipse plugin.
Now, my project breaks in eclipse b/c it sets the JDK to be (I think)
the system default (which is JDK 1.5), but my maven-compiler-plugin
settings in the pom specify 1.6. So maven compiles the sources, and
when I launch the project in eclipse, it throws an error saying the
class version is wrong.
Nothing very interesting in the config below. This problem did not
exist for me until I just opened up plugin snapshots -- which I think
I'll turn off. This is on:
$ mvn -version
Maven version: 2.0.9
Java version: 1.6.0_07
OS name: "mac os x" version: "10.5.6" arch: "x86_64" Family: "mac"
