maven import pom (BOM) own project from internal maven repository

We are trying to group maven dependencies inside a seperate maven POM-typed project.

We would like to use this as both a POM-type dependency inside the dependencies node aswell as a BOM (Bill of Materials) inside the de dependencyManagement.

We have an 2 repository inside the company. (Apache Archiva - 2.2.0). One of them is for Snapshots and one of them for releases.

When I try to use the snapshot version, everything works fine, but when i want to use the released version, i keep getting an error because it keeps looking for the dependency inside the central maven repository (where our pom is not located)

To me it seems like the POM-dependency is being searched inside the snapshot repository only.

<properties>
    ...
    <dependency.bla-slf4j-logback-BOM.version>1.0.1</dependency.bla-slf4j-logback-BOM.version>
    ...
</properties>
<dependencies>
    ...
    <dependency>
        <groupId>my.groupid</groupId>
        <artifactId>bla-slf4j-logback-BOM</artifactId>
        <version>${dependency.bla-slf4j-logback-BOM.version}</version>
        <type>pom</type>
    </dependency>
    ...
</dependencies>
<dependencyManagement>
    <dependencies>
        ...
        <dependency>
            <groupId>my.groupid</groupId>
            <artifactId>bla-slf4j-logback-BOM</artifactId>
            <version>${dependency.bla-slf4j-logback-BOM.version}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
        ...
    </dependencies>
</dependencyManagement>

errormessage:

[ERROR]     Non-resolvable import POM: Failure to find my.groupid:bla-slf4j-logback-BOM:pom:1.0.1 in http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced @ line 234, column 22 -> [Help 2]

used command:

mvn dependency:tree
  • maven version: Apache Maven 3.2.2
  • archiva version: Apache Archiva - 2.2.0

I checked our archiva, the artifact is present at the expected location. I also checked the local maven directory, the pom dependency was downloaded correctly.

Any ideas why this doesn't work for a released version of our POM-project (1.0.1), but does work for a Snapshot version (1.0.1-SNAPSHOT) of our POM-project.

Solution

  • The solution was to add the following block of xml to the maven settings.xml file.

    <mirrors>
    <mirror>
        <id>ourcentral</id> 
        <name>our central</name>
        <url>http://mavenrepourl.goes.here</url>
        <mirrorOf>central</mirrorOf>
    </mirror>
</mirrors>

    This causes it to check our internal maven repository as the central maven repository. (our maven repository has the default central repository as remote repository)
