Build of UI5 app fails with custom UI5 libs (via `includeDependencies`) using custom tasks => "Could not find custom task..."

[petermuessig]

Expected Behavior

When building an UI5 application project consuming a custom UI5 library project providing own build tasks, the build should be able to run this build task for this UI5 library project.

Current Behavior

The build fails with the issue that the tooling extension providing the custom build task cannot be found:

> SAPDevelop/temp/ui5-tooling-dep-issue  % npm run build:app

> ui5-tooling-dep-issue@1.0.0 build:app
> npm run build -w com.myorg.myapp


> com.myorg.myapp@1.0.0 build
> ui5 build --clean-dest

info ProjectBuilder Preparing build for project com.myorg.myapp
info ProjectBuilder   Target directory: ./dist
info ProjectBuilder   Requested dependencies:

⚠️  Process Failed With Error

Hey Peter, this works as designed.

For myapp to be able to use the ui5-tooling-stringreplace dependency, mylib needs to declare it within the package.json dependencies rather than devDependencies.

That's true, indeed... My mistake...
