Hi, I've encountered some errors when I tried to install an artifact manually with Maven 2. I wanted to install a jar from a local directory with the command mvn install:install-file -Dfile=jta-1.0.1B.jar But Maven gave a build error which reads like: Invalid task '.01B.jar': you must specify a valid lifecycle phase, or a goal in the format plugin:goal or pluginGroupId:pluginArtifactId:pluginVersion:goal Is there a mistake with my command?
