Execution default-cli of goal com.google.appengine:appengine-maven-plugin:1.9.32:update failed

[displayname via StackOverflow]

What I am trying to do is to deploy/update my web aplication using he google appengine plugin for maven.

Therefore I added the plugins in my pom.xml file:

<project>

    <!-- .. -->

    <profiles>
        <profile>
            <build>
                <pluginManagement>
                    <plugins>

                        <plugin>
                            <groupId>com.google.appengine</groupId>
                            <artifactId>appengine-maven-plugin</artifactId>
                            <version>${appengine.version}</version>
                            <configuration>
                                <enableJarClasses>false</enableJarClasses>
                                <version>${app.version}</version>
                            </configuration>
                        </plugin>

                        <plugin>
                            <groupId>com.google.appengine</groupId>
                            <artifactId>gcloud-maven-plugin</artifactId>
                            <version>${gcloud.plugin.version}</version>
                            <configuration>
                                <set_default>true</set_default>
                            </configuration>
                        </plugin>

                    </plugins>
                </pluginManagement>

                <plugins>
                    <plugin>
                        <groupId>com.google.appengine</groupId>
                        <artifactId>appengine-maven-plugin</artifactId>
                        <version>${appengine.version}</version>
                    </plugin>
                </plugins>

            </build>
        </profile>
    </profiles>
</project>

I also added the pluginGroup:

  <pluginGroups>
    <!-- pluginGroup
     | Specifies a further group identifier to use for plugin lookup.
    <pluginGroup>com.your.plugins</pluginGroup>
    -->
    <pluginGroup>com.google.appengine</pluginGroup>
  </pluginGroups>

However, if I call mvn appengine:update I am receiving
