Applying a patch at runtime in Maven

Question

I'm trying to install Giraph 1.1 but ran into an issue. According to this thread I should apply a patch to my installation. Unfortunately, my problem stems from that. I downloaded and copied the .patch file linked in there to the source folder and added the following to the pom.xml:

<plugins>

   <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-patch-plugin</artifactId>
    <version>1.2</version>
    <configuration>
      <patches>
        <patch>GIRAPH-1110.02.patch</patch>
      </patches>
...
</plugins>

Unfortunately when I run Maven with:

sudo mvn -Phadoop_yarn -Dhadoop.version=2.8.1 clean package -DskipTests

it still fails with the same error as it did before:

which clearly shows that the issue has not been patched. When I check the file manually, I can confirm that there's no change. If I change the file manually before compilation, the changes get discarded (I'm guessing the file gets redownloaded). Also can't run the installation with offline flag since it depends on downloading some dependencies. I'm at my wits end here.

My Maven version is 3.3.9.
