JanusGraph build failed (TinkerPop 3.2.4) - maven

Question

I cloned JanusGraph repo (d6b3d42) and build it without any problem. I need to use it with ThinkerPop 3.2.4 so I changed its version in pom.xml file. Then I run mvn clean install -DskipTests=true.

How can I build JanusGraph with TinkerPop 3.2.4 version?

Answer 1

Update the root pom.xml to add the Jitpack repository:
<repository>
<!-- for com.github.jeremyh:jBCrypt:jar -->
<id>jitpack.io</id>
<name>JitPack Package Repository</name>
<url>https://jitpack.io</url>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>
This repository was removed the pom.xml because newer versions of Apache TinkerPop do not have this dependency.
Reference from janusgraph-users Google group:
That dependency isn't found in Maven central, jbcrypt-0.4 is found in the jitpack.io repository. You'll need to add a remote repository for it. You could use the dependency:get command:
mvn dependency:get -DremoteRepositories="https://jitpack.io" -Dartifact="com.github.jeremyh:jBCrypt:jbcrypt-0.4"
When you run the command above, you will download the required jBCrypt dependency into your local Maven repository so that you can continue to build JanusGraph. If you're interested in building a distribution zip, similar to the ones you can find on the JanusGraph downloads page, use this command:
mvn clean install -DskipTests=true -Dgpg.skip=true -Pjanusgraph-release
Then you can find the distribution zip under janusgraph-dist/janusgraph-dist-hadoop-2/target/janusgraph-0.2.0-SNAPSHOT-hadoop2.zip.
