Maven Dependency Type
Hey guys,
I have a question regarding the maven dependencies section.
In order to put a dependency on a test jar, is it correct to specify <type>test-jar</type> or <type>test</type>?
I specified a dependency on project bar from project foo using <type>test<test> in a dependency section and the maven eclipse plugin ran successfully and eclipse set up my projects so that the module recognizes, but mvn package gives the following error:
[ERROR] Failed to execute goal on project statistics: Could not resolve dependencies for project com.mojiva:foo:jar:1.9.0-SNAPSHOT: Could not find artifact com.mojiva:bar:test:1.9.0-SNAPSHOT in mojiva
If I change it, to test-jar, the error goes away.
I know I have used <type>test</type> in the past and not had an issue. Did it change?
Also, I can't find the documentation on this. A pointer to the docs would be helpful.
Thanks to all!

test-jar, test does not exist. However, I typically declare always both:
"type" and "classifier" ("tests" here).

Because the maven-eclipse-plugin ignores classifiers, since Eclipise has no
concept for it. The plugin can only link Eclipse projects.

No. Did you use classifier "tests" in the past?

Makes sense as to why Eclipse does not discriminate.

Correct. I should have been more clear in my question. I am referring to
the artifact bar-1.9.0-SNAPSHOT-tests.jar.

Actually, that isn't true. It does deploy. At least it does for me. It
seems to deploy both to my local repo as well as to Nexus.
And if I add a dependency like this:
<dependency>
<groupId>${project.groupId}</groupId>
<artifactId>dao</artifactId>
<version>${project.version}</version>
<scope>test</scope>
<type>test-jar</type>
</dependency>
it works (whether it officially is supposed to). This dependency:
<dependency>
<groupId>${project.groupId}</groupId>
<artifactId>dao</artifactId>
<version>${project.version}</version>
<scope>test</scope>
<type>test</type>
</dependency>
does not.
That is my question. Thanks, guys!

Hi John,
the problem is that Eclipse doesn't know any difference between the normal classpath of an application and a test classpath that includes tests. For eclipse everything (application and test classes) are thrown into one basket. That's why you are able to build in Eclipse. As Jörg mentioned, in maven there is no such thing as a test-jar type dependency. I guess you are refering to the test-jar goal of the jar plugin. Unfortunately these test jars are usually not deployed in the local or any remote maven reposiories, so they only exist in your projects target directory.
One way to achieve what you want, would be to create an ordinary maven artifact containing the classes you want to share and to add a reference to that wherever you need it.
We usually have some artifacts, that we use only for testing. In order to use these classes in several artifacts tests, we usually strip out those shared resources into an artifact with a special suffix "test-support". Then all we need to do is to add an ordinary test-scoped dependency to that jar.
hope that helps,
Chris

Hey guys,
I have a question regarding the maven dependencies section.

I specified a dependency on project bar from project foo using <type>test<test> in a dependency section and the maven eclipse plugin ran successfully and eclipse set up my projects so that the module recognizes, but mvn package gives the following error:
[ERROR] Failed to execute goal on project statistics: Could not resolve dependencies for project com.mojiva:foo:jar:1.9.0-SNAPSHOT: Could not find artifact com.mojiva:bar:test:1.9.0-SNAPSHOT in mojiva
If I change it, to test-jar, the error goes away.
I know I have used <type>test</type> in the past and not had an issue. Did it change?
Also, I can't find the documentation on this. A pointer to the docs would be helpful.

uyou can have a look at http://maven.apache.org/ref/3.1-SNAPSHOT/maven-
core/artifact-handlers.html for a reference of default types and classifiers
