Jacoco Agent running with Dockerd/Tomcat: Error opening zip file or JAR manifest missing

[Michael Furmaniuk]

I have downloaded the 0.7.8 build from the Jacoco page: http://www.jacoco.org/jacoco/

In trying to set up my local Tomcat build, I would like to run the Jacoco Agent to get my test reports, I place the following configuration:

"JAVA_OPTS=-javaagent:/data/shared/jacoco/lib/jacocoagent.jar=includes=*,output=file,destfile=/data/shared/tests/jacoco/jacoco.exec"

When starting Tomcat I get the following in the Tomcat Log:

Jan 19 16:28:14 sandbox dockerd[1450]: Error opening zip file or JAR manifest missing : /data/shared/jacoco/lib/jacocoagent.jar

Jan 19 16:28:14 sandbox dockerd[1450]: Error occurred during initialization of VM

Jan 19 16:28:14 sandbox dockerd[1450]: agent library failed to init: instrument

Is there some other configuration I need to put in place?  Libraries are in the right location, I downloaded the Jacoco.0.7.8.zip archive and placed the files in the location noted.  Checking their JAR files I do see a Manifest file.  The Tomcat does run in a docker container, if that would make a difference.

java version "1.8.0_102"

Java(TM) SE Runtime Environment (build 1.8.0_102-b14)

Java HotSpot(TM) 64-Bit Server VM (build 25.102-b14, mixed mode)

I am running this on OSX Yosemite

Please check that file "/data/shared/jacoco/lib/jacocoagent.jar" exists inside of Docker container.

 

 The Tomcat does run in a docker container, if that would make a difference.

Please verify by yourself, whether problem caused by Docker or not - by doing without Docker.
