Hi,

I'm getting following warning:

```java
[WARNING] The following goals are not marked @threadSafe in Flink : Quickstart : Java:
[WARNING] org.apache.maven.plugins:maven-archetype-plugin:3.2.0:integration-test
[WARNING] org.apache.maven.plugins:maven-archetype-plugin:3.2.0:jar
[WARNING] org.apache.maven.plugins:maven-archetype-plugin:3.2.0:update-local-catalog
```

Could you please mark this plugin as threadSafe ?

No further details from [ARCHETYPE-614](https://issues.apache.org/jira/browse/ARCHETYPE-614?redirect=false)

Locate the implementations of the integration-test, jar, and update-local-catalog goals and inspect how their Maven plugin metadata declares thread safety. Run a parallel Maven build that produces the warning, then verify the warning is absent for all three goals after the change.
