mvn-gae-plugin suddenly broken - google-app-engine

Question

I'm not sure what happened but I've made not changes to my pom and have only done a clean install but now running my app with mvn gae:run gives me the following error:
[ERROR] Failed to execute goal net.kindleit:maven-gae-plugin:0.9.4:run (default-cli) on project geoip-service: Execution default-cli of goal net.kindleit:maven-gae-plugin:0.9.4:run failed: Plugin net.kindleit:maven-gae-plugin:0.9.4 or one of its dependencies could not be resolved: Failed to collect dependencies for net.kindleit:maven-gae-plugin:jar:0.9.4 (): Failed to read artifact descriptor for net.kindleit:gae-runtime:pom:1.7.5: Could not find artifact net.kindleit:maven-gae-parent:pom:0.9.6-SNAPSHOT in genius (our_own_repo_here)
I'm using the 1.7.2 version of the sdk so I'm not sure where the 1.7.5 could be coming from.

Answer 1

For the time being, you can use this ugly hack
<properties>
<gae.version>1.7.5</gae.version>
<gae-runtime.version>1.7.5.1</gae-runtime.version>
</properties>
<plugin>
<groupId>net.kindleit</groupId>
<artifactId>maven-gae-plugin</artifactId>
<version>${maven.gae.plugin.version}</version>
<configuration>
<unpackVersion>${gae.version}</unpackVersion>
<serverId>appengine.google.com</serverId>
<appDir>${webappDirectory}</appDir>
</configuration>
<dependencies>
<dependency>
<groupId>net.kindleit</groupId>
<artifactId>gae-runtime</artifactId>
<version>${gae-runtime.version}</version>
<type>pom</type>
</dependency>
</dependencies>
</plugin>

I still don't know what the issue was, I.e. who was pulling in gae-runtime of version 1.7.5 but this is the work around that worked for me. Add the following under your maven-gae-plugin in profile/build/plugins/plugin etc.
<dependencies>
<dependency>
<groupId>net.kindleit</groupId>
<artifactId>gae-runtime</artifactId>
<version>1.7.2</version>
<type>pom</type>
</dependency>
</dependencies>
