All Implemented Interfaces:

@Mojo(name="install-cdsdk",
      defaultPhase=INITIALIZE,
      aggregator=true)
public class InstallCdsdkMojo
extends AbstractCdsMojo

Install @sap/cds-dk in the current CAP Java project.
By default, this goal looks for an already installed @sap/cds-dk and skips installation if it was found. It doesn't validate the found version against the requested version to install and the installed @sap/cds-dk could be outdated. Add property -Dcds.install-cdsdk.force=true to the Maven command line to force the installation of a @sap/cds-dk in the configured version.

Since:

1.7.0
