Hi,

I am trying your tool to migrate a repository from my old nexus (2.X) server to a new one (3.Y). I want to migrate a whole repository, not only a singe artifact.

I was able to transfer single artifacts with the following call:

java -jar /tmp/maven-repository-provisioner-1.4.1-jar-with-dependencies.jar \
    -s "http://nexus2.domain.com/nexus/content/repositories/snapshots/" \
    ${N2CREDS} \
    -t "https://nexus3.domain.com/repository/snapshots/" \
    ${N3CREDS} \
    -a "de.example:my-app:0.0.1-SNAPSHOT"

But what I really want to do is transferring the whole repository with everything insinde, like that:

java -jar /tmp/maven-repository-provisioner-1.4.1-jar-with-dependencies.jar \
    -s "http://nexus2.domain.com/nexus/content/repositories/snapshots/" \
    ${N2CREDS} \
    -t "https://nexus3.domain.com/repository/snapshots/" \
    ${N3CREDS}"

But then, nothing happens, I only get a SUCCESS returncode but no artifacts are transferred. Any ideas? Or is it not possible to use your tool like this?

I made a copy of my Nexus2 Repository on filesystem, removed empty sub-directories (because they cause Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: -1) and tried to import that file system repo to my Nexus3 Repository with:

java -jar /tmp/maven-repository-provisioner-1.4.1-jar-with-dependencies.jar \
    -cd "/var/tmp/snapshots/" \
    -t "https://nexus3.domain.com/repository/snapshots/" \
    ${N3CREDS}"

This results in the same behaviour as above (SUCCESS returncode but nothing imported to my Nexus3).

Ok, after further reading I found out that a snapshot repository is not in scope (see #42). I will try with the releases repo now.

It is possible. You basically skip the download part and treat the repository that is local as the intermediary.

Here is how you can do it in terms of the commands... https://github.com/simpligility/maven-repository-tools/blob/master/maven-repository-provisioner/test.sh#L76

Thanks a lot. After understanding, that the tool is not mede for migrating SNAPSHOTS, I tried my releases repository and it worked perfectly. I will close this issue and try to convince my team, that SNAPSHOTS are temporary and should not be necessary to migrate at all.
