Preface

Gradle, a breakthrough building tool based on JVM. Gradle is rapidly becoming the choice of many open source projects and cutting-edge enterprise building systems, while also challenging legacy automated building projects.

Originally in the company to do the project, wrote a simple project based on gradle deployment of the script, today turned out to record 1, the following words do not say much, to a look at the details of the introduction.

The method is as follows:

1. build.gradle


buildscript {
 ext {
 env = System.getProperty("env") ?: "test"
 jvmArgs = "-server -Xms128m -Xmx128m -XX:NewRatio=4 -XX:SurvivorRatio=16 -XX:MaxTenuringThreshold=15 -XX:CMSInitiatingOccupancyFraction=80 -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -XX:+ExplicitGCInvokesConcurrent -XX:+DoEscapeAnalysis -XX:-HeapDumpOnOutOfMemoryError"
 if (env == "prod") {
 jvmArgs = "-server -Xms2g -Xmx2g -XX:NewRatio=4 -XX:SurvivorRatio=16 -XX:MaxTenuringThreshold=15 -XX:CMSInitiatingOccupancyFraction=80 -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -XX:+ExplicitGCInvokesConcurrent -XX:+DoEscapeAnalysis -XX:-HeapDumpOnOutOfMemoryError"
 }
 userHome = System.getProperty("user.home")
 osName = System.getProperty("os.name")
 }

2. build. gradle under the corresponding module


def mainClass = "com.hzgj.information.rest.user.run.UserServiceProvider"

 }

 home {
 role 'home'

 }


}
task deploy << {

 def roles = remote.findAll {

 it['roles'][0].toString().contains(currentEnv)

 }
 }
 }
}

3. How to use it

Step 1 Run first gradle copyAll -x test Performs a package operation, which will put all the dependent jar of the module

2. Enter the corresponding module to run gradle deploy -Denv=xxx -Dindex=xxx What do you mean? -Denv represents which 1 environment-Dindex specifies which node in that environment to publish

3. gradle start -Denv=xxx -Dindex=xxx Run the application in the current environment
