Error while installation

[shreyjairath]

I am following the install instructions in readme but it fails at step -
mvn install -DskipTests=true
inside titan repo, with following error:
Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.5.1:compile (default-cli) on project titan-berkeleyje: Compilation failure: Compilation failure:
[ERROR] error: error reading /Users/sjairath/.m2/repository/com/thinkaurelius/titan/titan-core/0.4.1-Lab41-SNAPSHOT/titan-core-0.4.1-Lab41-SNAPSHOT.jar; error in opening zip file

Its repeatedly trying to download these files just before it fails:
Downloading: http://download.oracle.com/maven/com/thinkaurelius/titan/titan-core/0.4.1-Lab41-SNAPSHOT/maven-metadata.xml
Downloading: https://oss.sonatype.org/content/repositories/snapshots/com/thinkaurelius/titan/titan-core/0.4.1-Lab41-SNAPSHOT/maven-metadata.xml

both downloaded files are failing checksum validation

@shreyjairath the Lab41 fork of titan is not published, so you have to build it locally yourself. Did you follow these instructions and it led you to this error?
% git clone https://github.com/Lab41/titan.git % cd titan % git checkout dendrite % mvn install -DskipTests=true

you may also need to clean out your .m2

[shreyjairath]

@cglewis yes, the steps mentioned by you led to this error. Also, I didn't have a local maven repo when I started out- so a new one must have been created.

I removed .m2 and the cloned titan repo and did the installation steps from scratch again - and it finished successfully this time. Can't say why it failed before.
