multi tech stack with npm_install

[skagithala-clgx]

Hi Team,

We have use case where multistack repo is configured and it is using gradle & Nodejs with packeto build pack and it is using common folder for dependencies resolutions. trying to install npm_install, failing with below errors
Issue:
it is unable to install npm_install

Task :frontend:npm_install
18:11:30 Caching disabled for task ':frontend:npm_install' because:
18:11:30 Build cache is disabled
18:11:30 Task ':frontend:npm_install' is not up-to-date because:
18:11:30 Task has not declared any outputs despite executing actions.
18:11:30 Starting process 'command '/workspace/frontend/.gradle/npm/npm-v6.14.10/bin/npm''. Working directory: /workspace/frontend Command: /workspace/frontend/.gradle/npm/npm-v6.14.10/bin/npm install
18:11:30 Successfully started process 'command '/workspace/frontend/.gradle/npm/npm-v6.14.10/bin/npm''
18:11:38 npm WARN tar ENOENT: no such file or directory, open '/workspace/frontend/node_modules/.staging/@schematics/update-38800c5d/LICENSE'

18:11:38 npm WARN tar ENOENT: no such file or directory, open '/workspace/frontend/node_modules/.staging/yaml-f611cfa4/dist/index.js'

below are the configurations
settings.gradle
rootProject.name = 'xyz'
include 'frontend'
include 'backend'
In build.gradle of project1 below line is mentioned for dependency

frontend/build.gradle contains buildFrontend.dependsOn npm_install
Backend/build.gradle contains
bootJar.dependsOn ':frontend:npm_install'
bootJar.dependsOn ':frontend:buildFrontend'

Project structure:
project1
project2
gradlew
gradlew.bat
settings.gradle

Could you please guide on mono repo configuration, provide if we have any documentation for the same.

I would suggest taking a look at the sample app here: https://github.com/paketo-buildpacks/samples/tree/main/java/java-node/gradle-node

It should be doing roughly what you're trying to accomplish.
