Exception occurred executing command line
Cannot run program “C:\Program Files\diffblue-cover-cli-

Hi Hemal,
It looks like a general issue with running CLI version of Cover (used to integrate into Eclipse) on your device.
First, I would see if you are seeing the same error when running dcover --version in a command line environment. Looking at the error you are seeing some basic things to check is that; dcover is executable, and that none of the dependencies are corrupt.
Please let me know how this goes
Kind regards,
Jane @ Diffblue
Hello Jane,
I tried running this command in cmd and it gives me this error
" dcover is not recognized as an internal or external command, operable program or batch file."
Hi @Hemal
Have you added the location of dcover to your Path environment variable?
If not; please do so, then restart your CLI session, and try running dcover --version again
Kind regards,
Jane @ Diffblue
Hi Hemal,
Were you able to get that set up?
If not, we have a Windows installer available to you which could help you with your set up.
I would be happy to send this as part of your trial; we can have a 1:1 session to go through the installation together. How does that sound?
Kind regards,
Jane @ Diffblue
Hello Jane,
1:1 season sounds great.
Please let me know when it is good time to conduct this season.
Thanks & Regards,
Hemal
Great - I will contact you directly to organise

@Jane_Walls i’m also facing the issue while using this as an external tool in Eclipse
can u help me pls …we are also at same stage i need to show this to my Project Manager in order to get for our team
Hi @Deep_Tomar
Of course, we would be happy to help you through this issue. It would be useful for us to know more information about the behaviour you are experiences as it may not be exactly the same as the original post. Are you please able to try running dcover --version in a command line environment?
This will isolate and show us directly what is happening when Eclipse is attempting to execute Cover, and therefore what the solution is.
Kind regards,
Jane @ Diffblue
PS C:\Users\Admin> dcover --version
2024.06.02-f*1c*04-licensed
PS C:\Users\Admin>
this is what i get
Hi @Deep_Tomar
Thank you - this shows us that Cover is on your path, and it has installed correctly in your system. This also means it is unlikely the same issue as the original post.
You mention you have had trouble running Cover from Eclipse.
Are you able to show me, and give more information about what issue Cover is having when running in Eclipse?
Kind regards,
Jane
Exception occurred executing command line.
Cannot run program “C:\Program Files\Diffblue\dcover” (in directory “C:\Users\Admin\Documents\BOXTRACKER\BoxTracker”): CreateProcess error=193, %1 is not a valid Win32 application
this is the error in Ecllipse while running
@Jane_Walls is it possible if we can get this resolve a bit faster so that i can use this and then give the demo to my team coz we actually are in hurry
Hi @Deep_Tomar
Please double-check the instructions at Using Cover CLI in Eclipse. The example given in the video is for a Linux system, where the executable is dcover, whereas you will want to choose dcover.bat for Windows.

Hi @Deep_Tomar
Now you have Diffblue Cover running, which is progress!
Diffblue Cover uses various build system (Maven/Gradle) commands to identify features of the Java project and to build/run tests etc. In this case, the build system (Maven) has produced an error. By default, Cover will use the Maven (or Gradle) wrapper script, if available. It is possible that this is not what you want. If you don’t want it to use the wrapper script (mvnw.cmd), you can rename or remove it and try again. If you do want it to use the wrapper script, see below.
This Maven command has been run by Diffblue Cover:
“C:\Users\Admin\Documents\BOXTRACKER\BoxTracker\mvnw.cmd -B -D output=diffblue.effective-pom.output.xml -D mdep.outputFile=diffblue-cp.txt -D mdep.pathSeparator=#SEP# -D includeScope=test -D skipTestOptimizer=true -D mdep.outputProperty=build.classpath -D “maven.ext.class.path=C:\Program Files\Diffblue\cover-buildsystem-maven-spy-jar-with-dependencies.jar” validate org.apache.maven.plugins:maven-help-plugin:3.2.0:effective-pom -am”
You can run it outside Diffblue Cover (i.e. on the command line), which will likely show the same error. The error in question reported by Maven is:
Standard error: The system cannot find the file C:\Users\Admin\Documents\BOXTRACKER\BoxTracker.mvn\wrapper\maven-wrapper.properties.
Note also the warning about support Java versions:
Diffblue provides only community support for Java version 10.0.2.
Diffblue supports LTS versions Java 8 351+, Java 11.0.17+,
Java 17.0.5+, or Java 21.0.1+ for production use.
In general, you are likely to get better results by using one of the LTS versions of Java, although that may not be related to the build system error you’ve seen.

These are informative messages (output codes) from Diffblue Cover, with suggested actions, intended to help the user take the next steps.
I’m glad to see that you were able to configure Eclipse to run Cover, and that the Maven issues seen previously have been resolved.
If you have specific questions at a later time, please get in touch by starting a new topic in this forum.
Thanks and enjoy using Diffblue Cover!
