[m2e-users] Error updating EAR projects

["Thorsten Heit" <thorsten.heit@xxxxxx>]

Hi,

with the latest Eclipse 4.7 (Oxygen) milestone M6
I'm having problems updating Maven projects that contain EAR modules:


Plug-in:  org.eclipse.core.jobs

I can't remember to have seen this message with the
4.7M5 milestone.

I'm using:

Does anybody know how to fix this?


I don't know it it is important, but the problematic
EAR projects basically contain the following snippet in their pom.xml's:


<properties>
  <implementation.version>${project.version}
(SVN rev. ${buildNumber})</implementation.version>
</properties>

<build>
  <finalName>myproject-${project.version}</finalName>

  <plugins>
    <plugin>
      <groupId>org.codehaus.mojo</groupId>
      <artifactId>buildnumber-maven-plugin</artifactId>
    </plugin>

    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-ear-plugin</artifactId>
      <version>2.10.1</version>
      <configuration>
        <version>5</version>
        <description>myproject</description>
        <displayName>myproject-${project.version}</displayName>
        <generateApplicationXml>true</generateApplicationXml>
        <archive>
          <manifestEntries>
            <Implementation-Version>${implementation.version}</Implementation-Version>
            <Implementation-Build>${buildNumber}</Implementation-Build>
            <Implementation-Date>${maven.build.timestamp}</Implementation-Date>
          </manifestEntries>
        </archive>
        <modules>
          <webModule>
            <groupId>${project.groupId}</groupId>
            <artifactId>myproject-war</artifactId>
            <contextRoot>/myproject</contextRoot>
          </webModule>
        </modules>
      </configuration>
    </plugin>
  </plugins>
</build>
