First build fails on Jenkins war

[Kalana Wijethunga]

Hi,

I am a newbie to Jenkins who is looking to contribute Jenkins. I am having some trouble in building the project for the first time. I am building Jenkins [1] on windows by typing the command "mvn clean package -pl war -am -DskipTests -Dfindbugs.skip" given in [2]. But there is a build failure on Jenkins war. I get the error "This app can't run on your PC" from windows and when i close that error, the build fails with the following error

"[INFO] Running 'yarn --mutex network' in F:\open source\jenkins\war

[ERROR] Access is denied."

I am assuming that the project can be built on Windows, as you haven't mentioned Ubuntu as prerequisite in building the project. I have tried running the command prompt as an adminstrator as well. Looks like node and yarn do not get permission to run command on the terminal. I have attached an image of the error for further reference. Appreciate your help in resolving this.

This definitely works in Windows (a few Jenkins developers are Windows
users). It appears as though there's an issue with yarn being run as a
subprocess during the JavaScript "compilation" phase (i.e.,
uglify/minify/etc). Do you have a firewall blocking yarn from making
HTTP requests?

Hi Matt,

Thank you for your reply.

I tried the build after turning windows defender off for both public and private networks. Still I am getting the same error.I dont have a virus guard installed.

By the sounds of it, it looks like you have a file access error of some sort when Maven goes to run yarn. You can verify the file permissions in the yarn directory it references to try and debug this.

Also, are you running on a 32-bit or 64-bit Windows?

Hi Matt, Slide,

I am running 64-bit windows.

The issue for node occurs with the following line at console. 

[INFO] Copying node binary from C:\Users\Kalana\.m2\repository\com\github\eirslett\node\6.10.2\node-6.10.2-win-x64.exe to F:\open source\jenkins\war\node\node.exe

I tried giving full control to all the users to the F:\open source\jenkins\war\node\node.exe folder with no luck. I tried to manually run the node.exe file in this location and when I open it,it gives me the error "This app cant run on your pc". It looks like the node and yarn packages in the build are not compatible with my windows for some reason. Can I manually install node and yarn on this location without allowing the build process to do it?

Thanks

other than that try removing c:\users\kalana\.m2\repository\com\github\eirslett  followed by a  "git clean -fdx" in your git checkout

Hi all,

The build suceeded after trying James's solution. Looks like the issue was due to a broken/corrupted node and yarn setups. Appreciate your help on resolving this.

Looking forward to contribute to Jenkins.

Thanks and Regards
