[m2e-users] m2e doesn't appear to be rerunning xjc on save of xsd

["KARR, DAVID" <dk068x@xxxxxxx>]

I've been working occasionally on a Maven app that uses CXF's XJC plugin to generate Java code from an XSD.  I'm pretty sure I've seen Eclipse regenerate the Java code when I saved the XSD, which then recompiles those classes.  This is a very good thing to happen automatically.

Recently I've noticed that this doesn't appear to be happening.  I just tested this now.  I made a relevant change to the xsd and saved it.  Eclipse went into "Building workspace", but it didn't appear to regenerate the code.  I checked the timestamp on the generated file, and it wasn't updated.  In this test case, I had also made a change in a Java class that references one of the generated types, and I was trying to reference a property that should have been there if the code was properly generated from the xsd.  If everything worked correctly, the red squigglies should have disappeared after I changed the xsd.

I believe this section of my pom is relevant:

		<pluginManagement>
			<plugins>
				<!--This plugin's configuration is used to store Eclipse m2e settings 
					only. It has no influence on the Maven build itself. -->
				<plugin>
					<groupId>org.eclipse.m2e</groupId>
					<artifactId>lifecycle-mapping</artifactId>
					<version>1.0.0</version>
					<configuration>
						<lifecycleMappingMetadata>
							<pluginExecutions>
								<pluginExecution>
									<pluginExecutionFilter>
										<groupId>org.apache.cxf</groupId>
										<artifactId>cxf-xjc-plugin</artifactId>
										<versionRange>[2.4.0,)</versionRange>
										<goals>
											<goal>xsdtojava</goal>
										</goals>
									</pluginExecutionFilter>
									<action>
										<execute />
									</action>
								</pluginExecution>
							</pluginExecutions>
						</lifecycleMappingMetadata>
					</configuration>
				</plugin>
			</plugins>
		</pluginManagement>

In Project Properties, I inspected the Lifecycle Mapping.  In the "generate-sources" phase, it had cxf-xjc-plugin:xsdtojava, with "execute" mapping, and source "pom".

I'm on STS 2.9.2 with the latest m2e.

What am I missing?
