[英]Documentation for the gradle run task?
After a long time of searching I was still not able to find any official documents for the gradle run
task.找了半天也没找到
gradle run
任务的官方文档。 I assume that is because it is actually JavaExec task type.我假设那是因为它实际上是JavaExec任务类型。
It also seems that the run
task is only available with the application plugin .似乎
run
任务仅适用于应用程序插件。 Its docs mention some of the available arguments such as --debug-jvm
and --args
(for passing command-line arguments to the application's main method).它的文档提到了一些可用的 arguments,例如
--debug-jvm
和--args
(用于将命令行 arguments 传递给应用程序的主要方法)。
What I actually wanted to find out how I can pass arguments to the JVM on the command-line, ie an equivalent of setting application { applicationDefaultJvmArgs = ".." }
.我实际上想知道如何在命令行上将 arguments 传递给 JVM,即相当于设置
application { applicationDefaultJvmArgs = ".." }
。
Help appreciated!帮助赞赏!
You're right, the run
task comes from the application plugin and it is a JavaExec
task.没错,
run
任务来自应用程序插件,它是一个JavaExec
任务。
A list of all configuration options is available in the documentation of the JavaExec task JavaExec 任务的文档中提供了所有配置选项的列表
You can configure options in your (groovy-)gradle file like so:您可以像这样在 (groovy-)gradle 文件中配置选项:
tasks.named('run', JavaExec) {
mainClassName = '...MainKt'
applicationDefaultJvmArgs = [ System.getProperty("jvmArgs") ]
classpath = sourceSets.netMain.runtimeClasspath
}
I have now written https://blog.jakubholy.net/2020/customizing-gradle-run-task/ which describes both how to customize the run
task and how to customize it on the command line:我现在写了 https://blog.jakubholy.net/2020/customizing-gradle-run-task/它描述了如何自定义
run
任务以及如何在命令行上自定义它:
apply plugin: 'application'
mainClassName = "my.app.Main"
run {
debugOptions {
enabled = true
server = true
suspend = false
}
systemProperty("my.defaultLogLevel", "debug")
environment("OTEL_EXPORTER", "zipkin")
jvmArgs=["-javaagent:aws-opentelemetry-agent-0.9.0.jar"]
}
As the application plugin documentation states, you can also enable debugging with --debug-jvm or specify arguments with --args="foo --bar".
正如应用程序插件文档所述,您还可以使用 --debug-jvm 启用调试或使用 --args="foo --bar" 指定 arguments。 And you can set application { applicationDefaultJvmArgs= []} to apply both to run and the generated start scripts of your distribution.
您可以设置 application { applicationDefaultJvmArgs= []} 以应用运行和生成的分发启动脚本。
