Error in building appengine sample application

[architsinha]

I was trying to build and run the sample apps for appengine present at : https://github.com/GoogleCloudPlatform/java-docs-samples/tree/master/appengine

I first tried the helloworld app present at : https://github.com/GoogleCloudPlatform/java-docs-samples/tree/master/appengine/helloworld and was able to successfully build and run it with the steps mentioned.

After that I tried to build the datastore sample app present at: https://github.com/GoogleCloudPlatform/java-docs-samples/tree/master/appengine/datastore
but the build was failing.
On running the command
mvn appengine:devserver
I got the following error:

After that I tried by adding option to skipTests and gave the following command:
mvn appengine:devserver -DskipTests

After running once with the option -DskipTests, whether I enable the option or not , both the commands
mvn appengine:devserver
and
mvn appengine:update
failed with the second error.

The details of the maven and JDK I am using are:
Maven : 3.5.0
JDK: 1.8.0_91

I did search for this error, however I could not find any solution which worked for me. Is this some issue in maven? Has anyone else observed this? Is there some configuration or step which I am missing which is leading to this?

Sorry not to have seen this earlier.

I was seeing that error last week and it disappeared this week. The easiest suggestion is that you update to the latest version of the SDK and try again.

You may wish to use -DskipTests=true. In the root directory, remove the reference to the parent project com.google.cloud.samples shared-configuration as it is including https://errorprone.info that appears to be causing an issue.
