问题
I'm trying to create hello-endpoint-framework using maven archetype
I used this command to build project.
mvn archetype:generate -Dappengine-version=1.9.63 -Djava8=true -DCloudSDK_Tooling=false -Dapplication-id=your-app-id -Dfilter=com.google.appengine.archetypes:
I set -Djava8=true because I want to run this in java8.
Here is pom.xml file.

After this I run this command mvn clean package to build project. And then I run mvn appengine:run but I got this error. appengine-maven-plugin:1.3.1 run failed non zero exit
I re-run my command with -e And here is what I got.

I understand only one error Project does not define required minimum version of Maven. I set the minimum version in pom but still same error.
After this I also tried to update gcloud components gcloud components update But not able to solve this error.
I'm using JDK10
I also have another question, Is this project is for java7 or for java8.
I want to run this project in java8 that's why I set -Djava8=true But I don't think this project is created for java8 enviroment, is it ? If not how can I do that ?
And what about appengine-maven-plugin error ? How can I solve this ? And why I'm seeing this, is there any problem in Cloud SDK ? Or there is anyother reason.
回答1:
As indicated here:
<properties>
<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
This is Java 7, so, if you want to run this with Java 8, you have to change both appearances of 1.7 to 1.8.
The error with appengine-maven-plugin is that you are trying to use Java 7, while saying to use Java 8 in the command.
