I've got a multi-module project with layout as below:
pom.xml
projA
trunk
pom.xml
projA1
pom.xml
projA2
pom.xml
In the parent's pom I've defined dependencyManagement
and properties
:
<properties>
<javaee-api.version>6.0</javaee-api.version>
<log4j.version>1.2.11</log4j.version>
</properties>
...
<dependencyManagement>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>${junit.version}</version>
</dependency>
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>${javaee-api.version}</version>
</dependency>
</dependencies>
</dependencyManagement>
pom.xml for projA2 contains:
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
</dependency>
pom.xml for projA1 contains:
<dependency>
<groupId>${project.groupId}</groupId>
<artifactId>projA2</artifactId>
<version>${project.version}</version>
</dependency>
In projA1 I'm using log4j but the dependency is transitive (from projA2).
Now when I run mvn dependency:tree -X
I get:
[WARNING] Invalid POM for mypackage:projA2:jar:1.0, transitive dependencies (if any) will not be available, enable debug logging for more details: Some problems were encountered while processing the POMs:
[ERROR] 'dependencies.dependency.version' for javax:javaee-api:jar is missing. @ line 37, column 15
[ERROR] 'dependencies.dependency.version' for log4j:log4j:jar is missing. @ line 56, column 15
but just below this lines I get:
[DEBUG] testArtifact: artifact=log4j:log4j:jar:1.2.11:compile
[DEBUG] includeArtifact: artifact=log4j:log4j:jar:1.2.11:compile
[DEBUG] startProcessChildren: artifact=log4j:log4j:jar:1.2.11:compile
[DEBUG] endProcessChildren: artifact=log4j:log4j:jar:1.2.11:compile
[DEBUG] testArtifact: artifact=javax:javaee-api:jar:6.0:provided

[DEBUG] startProcessChildren: artifact=javax:javaee-api:jar:6.0:provided
[DEBUG] endProcessChildren: artifact=javax:javaee-api:jar:6.0:provided
The only solution is to specify log4j version (<version>${project.version}</version>
) in projA2 pom.xml.
Question: what am I doing wrong :-(? I don't want to specify versions that are already defined in parent's dependencyManagement
section.
