I was encountering this error in Jenkins when it tried to build a project I was working on:
Caused by: java.io.IOException: Incompatible version 1007.
at org.jacoco.core.data.ExecutionDataReader.readHeader(ExecutionDataReader.java:127)

The problem was due to a breakage/bug in the jacoco-maven-plugin. To fix, simply add a version in your pom.xml, like so:
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.4.201502262128</version>
<executions>
<execution>
<goals>
<goal>prepare-agent</goal>
</goals>
</execution>
</executions>
</plugin>
That’s it!
