I can run Maven 2.0.0 with an External Tool definition (using Eclipse 3.2M4):

<?xml version="1.0" encoding="UTF-8"?>
<launchConfiguration 
type="org.eclipse.ui.externaltools.ProgramLaunchConfigurationType">
<stringAttribute key="org.eclipse.ui.externaltools.ATTR_TOOL_ARGUMENTS" 
value="-Xmx384M&#13;&#10;-cp 
&quot;${maven_2_home}/core/boot/classworlds-1.1-alpha-2.jar&quot;&#13;&#10;-Dclassworlds.conf=&quot;${maven_2_home}/bin/m2.conf&quot;&#13;&#10;-Dmaven.home=&quot;${maven_2_home}&quot;&#13;&#10;org.codehaus.classworlds.Launcher&#13;&#10;${string_prompt}"/>
<stringAttribute key="org.eclipse.debug.core.ATTR_REFRESH_SCOPE" 
value="${project}"/>
<listAttribute key="org.eclipse.debug.ui.favoriteGroups">
<listEntry value="org.eclipse.ui.externaltools.launchGroup"/>
</listAttribute>
<stringAttribute key="org.eclipse.ui.externaltools.ATTR_WORKING_DIRECTORY" 
value="${project_loc}"/>
<stringAttribute key="org.eclipse.ui.externaltools.ATTR_LOCATION" 
value="${system_property:java.home}/bin/java.exe"/>
<booleanAttribute key="org.eclipse.debug.core.appendEnvironmentVariables" 
value="true"/>
</launchConfiguration>

You just have to define maven_2_home in the "Preferences/Debug/String 
Substitution" for your Maven 2 home.
