DeployUtils

Deploy to Embedded Targets in both Java and C++.

For all projects, you can define deployment targets and artifacts. The deploy process works over SSH/SFTP and is extremely quick.

For the previous functionality for native library building, see edu.wpi.first.NativeUtils

Commands: gradlew deploy will deploy all artifacts gradlew deployStandalone will deploy all artifacts marked for standalone use with allowStandaloneDeploy gradlew deploy<artifact name><target name> will deploy only the specified artifact to the specified target

Properties: gradlew deploy -Pdeploy-dirty will skip the cache check and force redeployment of all files gradlew deploy -Pdeploy-dry will do a 'dry run' (will not connect or deploy to target, instead only printing to console)

Installing plugin

Include the following in your build.gradle

plugins {
    id "edu.wpi.first.DeployUtils" version "<latest version>"
}

See https://plugins.gradle.org/plugin/edu.wpi.first.DeployUtils for the latest version

            timeout = 3             // Timeout to use when connecting to target. Default: 3 (seconds)
            failOnMissing = true    // Should the build fail if the target can't be found? Default: true
