Elliotte Rusty Harold commented on MDEP-791:
--------------------------------------------
Using the test project linked above (MDEP-791.zip) I failed to reproduce this.
Everything worked exactly as I expected,both on compile and analysis. I did
have to change the compiler version to 1.8 in case that's significant. To be
specific:
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>${jackson.version}</version>
<scope>compile</scope>
</dependency>
caused
[WARNING] Non-test scoped test only dependencies found:
[WARNING] com.fasterxml.jackson.core:jackson-core:jar:2.13.1:compile
and
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>${jackson.version}</version>
<scope>test</scope>
</dependency>
fixed this to get:
[INFO] --- maven-dependency-plugin:3.3.0-SNAPSHOT:analyze (default-cli) @ tstp
---
[INFO] No dependency problems found
and did not break the build. mvn compile still worked. For the record
elharo-macbookpro1:tj elharo$ mvn -v
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /opt/java/maven
Java version: 1.8.0_302, vendor: Azul Systems, Inc., runtime:

Default locale: en_US, platform encoding: UTF-8

As of now I am unconvinced there is any bug to be fixed around this, either in
the dependency analyzer, plugin, or maven resolution. This is, of course,
subject to revision on more evidence. However right now it seems that if there
is an issue here, it is more subtle and specific than we yet understand.

> Key: MDEP-791
> URL: https://issues.apache.org/jira/browse/MDEP-791
> Project: Maven Dependency Plugin
> Issue Type: Bug
> Affects Versions: 3.2.0, 3.3.0
> Reporter: Slawomir Jaranowski
> Priority: Critical
> Attachments: MDEP-791.zip
>
>
> When we use some dependency in test classes which is not used in production
> code but is required as transitive dependency for other used in production
> code - such dependency should not be included in {*}{{Non-test scoped}}{*}.
> Example:
> * test code use {{ObjectCodec}} from {{jackson-core}}
> * production code use only {{ObjectMapper}} from {{jackson-databind}}
> * production code don't use any classes from {{jackson-core}}
> {{jackson-core}} is needed by {{jackson-databind}} and must by in compile
> scope so should not be reported as {{Non-test scoped}}
