The plugin fails when it can't find a revision

[alexnederlof]

The plugin fails when it can't find a revision. I think it happend because someone amended a commit. It could also be because travis doesn't fetch all revisions.

You can reproduce the problem like this:

git clone --depth=100 --quiet --branch=branchname git://github.com/crawljax/crawljax.git
cd crawljax
git checkout -qf 8c2e0f52d27c33df5e1c4c2deec472b1e138d67a
mvn clean package -DskipTests=true

This results in the error:

[ERROR] Failed to execute goal pl.project13.maven:git-commit-id-plugin:2.1.4:revision (default) on project crawljax-core: Execution default of goal pl.project13.maven:git-commit-id-plugin:2.1.4:revision failed: Unable to calculate distance between [commit 8c2e0f52d27c33df5e1c4c2deec472b1e138d67a 1359301377 ----sp] and [commit c8c9b49da0750d39f51b282e29f70672fb657b65 1356953576 ----sp]: Missing commit a19d505b92d4e73d39ab554cff26dc59dc8e25a9 -> [Help 1]

Here's an example of a failed build

I don't mind that it doesn't work, but it shouldn't break the build IMHO.

Hey Alex,
thanks for reporting this!

Yeap I see why and can imagine other build servers doing flat checkouts too... Though on a private server you could control that... but not so much on travis.

How about we add an option similar to failOnNoGitDirectory, which would be for example... failOnUnableToExtractRepoInfo = false - that'd save the build from failing on travis :)

I'd rather hide it under an option to allow users to decide if this is a very bad situation for them of if they just don't care.

Sounds good enough? :)

[alexnederlof]

Sounds perfect! It's just a use-case for Travis as far as I know. Jenkins doesn't have the problem.

Thanks!

Is there a workaround for this in the meantime? Something that I can do in git to make it work? Just hit this as a blocker from me checking in my POM updates.

[alexnederlof]

My work around was to activate the plugin only with certain profiles.

My problem is that I am using bamboo for CI and I actually want it to produce the git.properties file. I was hoping for a way to "repair" git so that the plugin would still work. Sounds like if there is a flag that just ignore the git.properties not being produced it wouldn't work for me.

I'm on it guys :-) Cheers from a Cafe in Kraków.

Can you fix this?

PS: you should change LN 319 of GitCommitIdMojo.java to a catch Exception instead of a IOException and it should work again.

[rmetzger]

I think you can increase the "clone depth" of travis in the .travis.yml file with:

git:
  depth: 500

[TheSnoozer]

The latest version of the plugin has two options to bypass any kind of exception:

<failOnNoGitDirectory>false</failOnNoGitDirectory>
<failOnUnableToExtractRepoInfo>false</failOnUnableToExtractRepoInfo>

failOnUnableToExtractRepoInfo was introduced with this issue
failOnNoGitDirectory was introduced with #26

Thanks for reporting and the support to track the problem down.
