To call an npm external command from Groovy, you can use the ProcessBuilder class in Java, which Groovy can utilize. You can create a new ProcessBuilder object and pass the npm command as a list of strings. Then, you can execute the command using the start() method of the ProcessBuilder object.
Here's an example of how you can call an npm external command from Groovy:
1 2 3 4 5 6 7 8 9 10 11 |
def command = ["npm", "install", "package-name"] def processBuilder = new ProcessBuilder(command) def process = processBuilder.start() process.waitFor() if (process.exitValue() == 0) { println "npm command executed successfully" } else { println "npm command failed" } |
In this example, we are calling the npm command npm install package-name. You can replace package-name with the actual package name you want to install using npm. The waitFor() method waits for the process to complete before continuing with the execution. Finally, we check the exit value of the process to determine if the npm command was executed successfully or not.
