DD4T 2 Java and Maven Build Failing

Question

I'm trying to Build DD4T 2 Java, using the following POM's and Maven (with version changed from 2.0.6-SNAPSHOT to 2.0.5. I am using the 'cd-8.1.0' profile for the CIL / CIS dependencies

• POM - https://github.com/dd4t/dd4t-2-java/blob/develop/dd4t-test-spring-web/pom.xml
• Parent POM - https://github.com/dd4t/dd4t-2-java/blob/develop/pom.xml

90% of the build is fine, but I get the following errors stopping the successful build.

[WARNING] The POM for com.tridion:cd_ambient:jar:8.1.0 is missing, no dependency information available

[WARNING] The POM for com.tridion:cd_cache:jar:8.1.0 is missing, no dependency information available

[WARNING] The POM for com.tridion:cd_core:jar:8.1.0 is missing, no dependency information available

[WARNING] The POM for com.tridion:cd_model:jar:8.1.0 is missing, no dependency information available

[WARNING] The POM for com.vs.ezlicrun:easylicense:jar:2.5 is missing, no dependency information available

Answer 1

These dependencies aren't available from maven central. You need to host those yourself. To find out which items are hosted on Maven central:

Check http://search.maven.org/#search%7Cga%7C1%7Cg%3A%22com.tridion%22

So they can't be resolved without hosting them yourself.

Use Artifactory or Sonatype Nexus to make this happen. The instructions for hosting the items yourself are on Github: https://github.com/dd4t/dd4t-2-java/wiki/Dependency-Management

Update: There are newer versions of these items available on maven central (Except the easlicense jar) you could also try to get things working with those dependencies.

Answer 2

It is because Maven look for dependencies in your local repository first, if not found there then in Maven Central.

All those missing dependencies are neither available in your local repository nor in Maven Central Repository. I came across the same problem and what i did is following:

1. Copied all the jars from my SDL Web8 setup folder[Most of them are present in "Content Delivery"] some of them were not there i searched them in maven central too, like. http://mvnrepository.com/artifact/com.tridion/cd_model/8.1.1-1005
2. Once i got all the jars, i placed them in one folder and renamed them as expected by my pom(like in your case it should look like cd_ambient-8.1.0)
3. After getting all of them renamed, made a batch file "maven-install.bat" which contained following maven commands[You can run them one by one too.]

    REM see DD4T dependency naming on https://github.com/dd4t/dd4t-2-java/blob/develop/README.md

    @echo off
    rem Install Tridion Content Delivery libraries and necessary third-party libraries in the local Maven repository

    echo Installing Tridion Content Delivery libraries into the local Maven repository...
    call mvn install:install-file -DgroupId=com.tridion -DartifactId=cd_ambient         -Dversion=8.1.0 -Dpackaging=jar -Dfile=cd_ambient-8.1.0.jar
    call mvn install:install-file -DgroupId=com.tridion -DartifactId=cd_cache           -Dversion=8.1.0 -Dpackaging=jar -Dfile=cd_cache-8.1.0.jar
    call mvn install:install-file -DgroupId=com.tridion -DartifactId=cd_core            -Dversion=8.1.0 -Dpackaging=jar -Dfile=cd_core-8.1.0.jar
    call mvn install:install-file -DgroupId=com.tridion -DartifactId=cd_model           -Dversion=8.1.0 -Dpackaging=jar -Dfile=cd_model-8.1.0.jar

    echo Installing third-party libraries into the local Maven repository...
    call mvn install:install-file -DgroupId=com.vs.ezlicrun -DartifactId=easylicense -Dversion=2.5 -Dpackaging=jar -Dfile=easylicense-2.5.jar

    echo Finished
    pause

Moved this maven-install.bat file in the same folder where i placed all my jars. And by running this file, all my mentioned jars got installed in my local maven repository.

Build you project and these jars will be referenced and will become part of your project's Maven Dependencies.
