I'm trying to run a custom task from inside a regular task.
My custom task is:
class SshTask extends DefaultTask {
String user
String host
String command
@TaskAction
void run() {
project.exec {
commandLine 'ssh', "$u...@$host", command
}
}
}
My regular task is :
task deploy {
description = 'Deploy the download to remote server. Specify $user,
$host,
and $deploymentDir.'
doLast {
ssh = new SshTask()
ssh.configure {
user = server.user
host = server.host
command = "mkdir -vp $server.dir"
}
ssh.execute()
}
}
However, this fails with :
* Exception is:
org.gradle.api.tasks.LocationAwareTaskExecutionException: Build file
'/home/ceefour/project/Bippo/magento-downloader/build.gradle'
Execution failed for task ':deploy'.

It means it fails during :
ssh = new SshTask()
What is the proper way to execute SshTask ? I don't want to create a named
task for it.
Also SshTask may also be called from inside another custom task, so SshTask
is not a "goal" but it's an "action".
Thank you.
