So, after downloading Node.js and putting it in my path like so:

export PATH=/local_static/node-v6.11.0-linux-x64/bin:$PATH

and running gradle:

./gradlew build --stacktrace

I get this error:

* Exception is:

While if I do:
 npm version

I get:

{ npm: '3.10.10',
  ares: '1.10.1-DEV',
  http_parser: '2.7.0',
  icu: '58.2',
  modules: '48',

  openssl: '1.0.2k',
  uv: '1.11.0',
  v8: '5.1.281.102',
  zlib: '1.2.11' }


Any suggestions?

Thanks.

Hi Scott,

Can you re-run your build again, but use the debug flag and send us the full output?

./gradlew build --debug

I'm curious to see what is going on there on your local box.

Regards,

Jon

Thanks.

Thanks Scott.

The error itself looks really odd since it mentions that the path "/local_static/IdeaProjects/labkey_trunk/server/modules/core" doesn't exist, but I'm assuming it does on your system, yes?

Does the same problem come back up if you do a "gradlew deployApp" or "gradlew cleanbuild deployApp"?

Regards,

Jon

Hi, Scott,

 It looks like the second error message is different than the first. If you run the command 'npm prune' in the server/modules/core directory (just by itself, and not using Gradle) does it succeed?

Susan

Yes to the above:

1. This path exists: '/local_static/IdeaProjects/labkey_trunk/server/modules/core'

2. Running 'npm prune' in server/modules/core directory succeeds.

3. Running './gradlew cleanbuild deployApp' completed successfully.

Thanks!

Hi Scott,

Thanks for confirming.

Unless I'm mistaken, I think you shouldn't be running things as "gradlew build", but rather as "gradlew deployApp".

If you were running "gradlew build" like it was "ant build" when we were using Ant previously, that would need to change to "gradlew deployApp" instead.

Our docs here show the old ant syntax and the new gradle ones that should be used instead. Knowing that you were able to do "gradlew cleanbuild deployApp" successfully, that is the equivalent of "ant rebuild", which should get you up and running now.

https://www.labkey.org/Documentation/wiki-page.view?name=gradlebuild

Does that make sense?

Regards,

Jon

Yes, that makes sense.

I had been running 'gradlew deployApp' up until now.

I guess the state of the build became such that a 'cleanbuild' became necessary.

I think I'm good now.

Scott

Would you please add information about this dependency on Node.js to this wiki page:
https://www.labkey.org/Documentation/wiki-page.view?name=devMachine

Thanks.

Hi Andy,

I've requested for our docs team to update the dev doc with the additional details on node.js

Regards,

Jon

I recently got the same error as Scott but doing './gradlew cleanbuild deployApp' did not resolve the issue. A response to a similar issue on stackoverflow (https://stackoverflow.com/questions/33546759/gradle-occurred-starting-process-command-npm-on-mac/) indicated that './gradlew --stop' has resolved a similar issue. I'm not sure why stopping the gradle daemon allowed './gradlew cleanbuild deployApp' to successfully complete, but it worked for me so I thought I'd pass it on.
