npmInstall task fails if the nodeModulesDir doesn't exist

[MHarris021]

When running the npmInstall task, if the nodeModulesDir doesn't exist the task will fail.
Adding this code:
`
task createNodeModulesDir << {
if (!nodeModulesDir.isDirectory()) {
nodeModulesDir.mkdirs()
}
}

npmInstall.dependsOn createNodeModulesDir
`

fixes the problem, but it would be nice not to have to do this.

This will break initial builds if the nodeModulesDir is included in the .gitignore file

I'm having the same issue... but instead of adding the createNodeModulesDir task, I'm adding it inside the node {} section, so mine looks like this:

node {
    version = '6.2.0'
    npmVersion = '3.9.0'
    distBaseUrl = 'https://nodejs.org/dist'
    download = true
    workDir = file("${project.projectDir}/nodejs")
    nodeModulesDir = file("${project.projectDir}/node_modules")
    if (!nodeModulesDir.isDirectory()) {
        nodeModulesDir.mkdirs()
    }
}

Your workaround is great, but I think it's a bit cleaner on the node section.

Of course, I hope this is fixed soon, and just add the folder creation on the plugin code instead.
