使用Maven-Gae和Google Eclipse插件时出错（GPE）

Question

I read the the last GPE integrated well with maven projects.

So I create a maven project from cmd line using the maven-gae-plugin.

Then imported into eclipse as a maven project.

However when I run it as "Web Application" (GPE) it fails with this error:

Unable to discover the Google App Engine SDK root but was instead loaded from file:/Users/neo/.m2/repository/com/google/appengine/appengine-tools-sdk/1.6.6/appengine-tools-sdk-1.6.6.jar. Specify -Dappengine.sdk.root to override the SDK location.

In project's Properties -> Google -> Google App Engine, I've the sdk point to /Users/neo/.m2/repository/com/google/appengine/appengine-java-sdk/1.6.6/appengine-java-sdk-1.6.6 (which is a valid sdk directory).

What I am doing wrong?

Answer 1

We also ran in the this problem. It seems to be a class loading problem. Simply move tools up on the list so it loads first.

1. Go to Run -> Run Confiurations ...
2. Select your app under " Web Application "
3. Click " Classpath " tab
4. highlight the appengine-tools jar and choose " Up " so it moves above your project.

Answer 2

Unzip the file appengine-tools-sdk-1.6.6.jar and it will create a folder appengine-tools-sdk-1.6.6

It will work if you put the following in VM arguments in your run configuration

-Dappengine.sdk.root=/Users/neo/.m2/repository/com/google/appengine/appengine-tools-sdk/1.6.6/appengine-tools-sdk-1.6.6
