  - Downloader(org.ysb33r.grolifant5.api.core.ConfigCacheSafeOperations projectOperations)
    
    Creates a Node downloader.
    Parameters:
    projectOperations - Project operations context.
    Since:
    4.0
  - @Deprecated Downloader(org.ysb33r.grolifant5.api.core.ProjectOperations projectOperations)
    
    Creates a Node downloader.
    deprecated:
    Use the constructor with org.ysb33r.grolifant5.api.core.ConfigCacheSafeOperations instead.
    
    Parameters:
    projectOperations - Project operations context.
    Since:
    0.10
- Method Detail
  - File getNodeExecutablePath(String version)
    
    Returns the path to the node executable. Will force a download if not already downloaded.
    Returns:
    Location of node or null if not a supported operating system.
  - @SuppressWarnings(value: UnnecessaryGetter) File getNpmExecutablePath(String version)
    
    Returns the path to the included npm-cli.js Node.js executable JavaScript. Will force a download if not already downloaded.
    Returns:
    Location of npm-cli.js or null if not a supported operating system.
  - @Override URI uriFromVersion(String ver)
    
    Provides an appropriate URI to download a specific tag of NodeJS.
    Parameters:
    ver - Version of Node to download
    Returns:
    URI for a supported platform; null otherwise.
  - @Override protected File verifyDistributionRoot(File distDir)
    
    Validates that the unpacked distribution is good.
    The default implementation simply checks that only one directory should exist and then uses that. You should override this method if your distribution in question does not follow the common practice of one top-level directory.
    Parameters:
    distDir - Directory where distribution was unpacked to.
    Returns:
    The directory where the real distribution now exists. In the default implementation it will be the single directory that exists below distDir.
    Throws:
    DistributionFailedException if distribution failed to meet criteria.
