Hello,
I am having the following issue with artifact resolution in the Maven reactor.
My project layout resembles the following:
--> Parent POM
--> POM A (packaging: pom)
--> POM B (packaging: jar)
"POM A" and "POM B" have "Parent POM" as parent. "Parent POM" has "POM A" and
"POM B" as submodules. All projects inherit their version from the parent POM.
"POM B" has a dependency on "POM A", which has dependencies on several other
artifacts and is used according to section "3.6.1. Grouping dependencies" in
http://www.sonatype.com/books/mvnref-book/reference/pom-relationships-sect-pom-best-practice.html.
When I execute "mvn package" on the parent POM, the build results in the
following error:
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Failed to resolve artifact.
Missing:
----------
1) mygroup:A:pom:1.0-SNAPSHOT
Path to dependency:
1) mygroup:B:jar:1.0-SNAPSHOT
2) mygroup:A:pom:1.0-SNAPSHOT
Debug output reveals the following error:
[DEBUG] WARNING: A dependency of the current project (or of one the plugins
used in its build) was found in the reactor,
but had not been built at the time it was requested. It will be resolved from
the repository instead.
Current Project: Unnamed - mygroup:B:jar:1.0-SNAPSHOT
Requested Dependency: mygroup:A:pom:1.0-SNAPSHOT
NOTE: You may need to run this build to the 'compile' lifecycle phase, or
farther, in order to build the dependency artifact.
So I am wondering if this is a bug. Dependencies on POM projects in the reactor
should not be handled different than dependencies on JAR-projects.
The content of POM file for project A is:
<project xmlns="http://maven.apache.org/POM/4.0.0";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/maven-v4_0_0.xsd";>
<modelVersion>4.0.0</modelVersion>
<parent>
<artifactId>parent</artifactId>
<groupId>mygroup</groupId>
<version>1.0-SNAPSHOT</version>
</parent>
<artifactId>A</artifactId>
<packaging>pom</packaging>
</project>
The content of POM file for project B is:
<project xmlns="http://maven.apache.org/POM/4.0.0";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/maven-v4_0_0.xsd";>
<modelVersion>4.0.0</modelVersion>
<parent>
<artifactId>parent</artifactId>
<groupId>mygroup</groupId>
<version>1.0-SNAPSHOT</version>
</parent>
<artifactId>B</artifactId>
<packaging>jar</packaging>
<dependencies>
<dependency>
<groupId>${project.groupId}</groupId>
<artifactId>A</artifactId>
<version>${project.version}</version>
<type>pom</type>
</dependency>
</dependencies>
</project>
Thanks a lot,
Florian
