Critical Description
One of the project that I was looking into has these relevant configurations:
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
<plugin>
<artifactId>maven-dependency-plugin</artifactId>
<version>3.1.2</version>
<configuration>
<failOnWarning>true</failOnWarning>
</configuration>
<executions>
<execution>
<goals>
<goal>analyze-only</goal>
</goals>
</execution>
</executions>
</plugin>
<dependency>
<groupId>org.hamcrest</groupId>
<artifactId>hamcrest</artifactId>
<version>2.2</version>
<!-- not scoped to test -->
</dependency>
The build succeeds as expected on executing `mvn clean verify` (apache-maven-3.6.3). I have now, made a change in the properties to *upgrade* the dependency plugin version:
<version>3.2.0</version>
and the logs on the terminal read
> [INFO] — maven-dependency-plugin:3.2.0:analyze-only (default) @ java-8-matchers —
> [WARNING] Non-test scoped test only dependencies found:
> [WARNING] org.hamcrest:hamcrest:jar:2.2:compile
leading to a failure(because of warning)! Why/How is the dependency treated differently with the upgrade in version? Any way to fix this?
----------
If it might be of help, the debug logs for this goal reads:
```

```
Reproducible with Java-17(since that was the reason for me to upgrade from 3.1.2 to 3.2.0) using:
1. Git checkout this branch.
2. Configure maven to use Java-17.
3. Edit the `failOnWarning` property to `true`.
4. Execute `mvn clean verify`.
