Using Docker Containers - Best Practice

When running Detect for Jenkins using the DETECT_JAR environment variable in a pipeline that has a Docker agent, remember to mount the Detect JAR as a volume.

For example, if you've installed the jar on a node, the JAR won't be accessible from your docker agent unless you either put it somewhere you regularly include, or if you mount the path to the jar. Refer to Docker documentation for more information.

This is accomplished by adding: -v $DETECT_JAR:$DETECT_JAR to your Docker arguments, which is shown in the following example. 

pipeline {
    agent {
        docker {
            ...
            args '-v $DETECT_JAR:$DETECT_JAR'
        }
    ...
...

Applies when running Detect for Jenkins with a local JAR (which requires setting the DETECT_JAR environment variable).
