如何为Grails2.5创建一个简单的构建脚本

我已经阅读了文档，它给出了结构，但没有提供任何关于如何创建实际逻辑的帮助

我想构建一个非常简单的脚本，它进行清理，创建war，创建源代码的zip（没有目标目录，也没有任何svn目录），并创建migrations目录的tar（理想的gzip），这样就可以与liquibase一起使用。这3个工件中的每一个都应该在其名称中包含应用程序版本（就像现有的“GrailsWar”一样）

项目结构如下所示：

svn
main-app
   grails-app
       migrations
       target
       :
exploded-plugin-1
   grails-app
   :
exploded-plugin-2
   grails-app
   :

这就是我所取得的成绩：

includeTargets << grailsScript("_GrailsInit")

target(packageUs: "Creates war, zips source, tars liquibase scripts") {
    depends(clean, war-us, zip-source, tar-liquibase)
}

setDefaultTarget(packageUs)

target ("war-us" : "creates war") {
    ant.war()  // this was a guess at calling the existing war - it doesnt work
}

target ("zip-source" : "zips sources") {
  // cd to top dir of project, i.e. above the app.
}

target ("tar-liquibase":"produces tar of migrations dir") {
    // tar up the migrations dir
    // name it with the app-version
    // put it in the target dir along side the war etc.
}

target ("clean") {
  // call the default clean some how, or cd to target dir, and delete everything
}

除了链接中非常基本的概述之外，我找不到任何示例脚本或文档

我甚至不能让ant.echo（）工作-intellij说只有一个ant.echo函数接受LinkedHashmap、字符串和闭包，但ant文档说echo只接受“消息”字符串。LinkedHashmap、字符串和闭包应该是什么？我尝试了至少30种不同的变体，都不起作用

includeTargets在谷歌搜索和浏览了一下grails核心脚本之后，我成功地创建了一个脚本，实现了您在问题中提到的功能

    import grails.util.Metadata

    includeTargets << grailsScript("_GrailsInit")
    includeTargets << grailsScript("_GrailsClean")
    includeTargets << grailsScript("_GrailsWar")

    target(pack: "Creates war, zips source, tars liquibase scripts") {
        depends(cleanAll, war)

        String appVersion = Metadata.current[Metadata.APPLICATION_VERSION],
               zipFileName = "${basedir}/target/sources-${appVersion}.zip",
               tarFileName = "${basedir}/target/migrations-${appVersion}.tar.gz"

        println "Creating Sources Zip"
        ant.delete(file: zipFileName)
        ant.zip(destfile: zipFileName, basedir: basedir, excludes: "**/target/**  **/.idea/** **/.classpath/** **/.iml/**")

        println "Creating Migrations Tar Ball"
        ant.delete(file: tarFileName)
        ant.tar(destfile: tarFileName, basedir: "${basedir}/grails-app/migrations")
    }

    setDefaultTarget(pack)

导入grails.util.Metadata
includeTargets哇，你是在谷歌上找到的吗？我在谷歌上搜索示例或文档已经好几天了，结果大部分是空白的。我确实找到了一个简单的方法来获取app.version：“xxx_${metadata.app.version'}”你说得对，除了脚本中可用的应用程序属性列表，谷歌搜索并没有给我提供太多。我主要从grails核心脚本源中得到帮助。“xxx_${metadata.'app.version'}”元数据从哪里来？它是自动注入的吗？奇怪的是，使用warMain依赖项创建的战争不起作用。它们产生的战争与执行“grails战争”不同2个字节，当放到tomcat上时，它们无法连接到db（连接被拒绝）。这非常奇怪。我试着仅仅依靠“战争”，它会产生相同的结果-一个与grails war不同几个字节的war，以及一个无法连接到db（无法创建连接池）的war。这可能是因为它使用了错误的环境吗？grails war=production，也许这是在尝试使用dev？

target ("war-us" : "creates war") {
   ant.echo(message:"hello") // this compiles and runs, but does nothing.
   println "hello there"  // this does work.
   // ant.war(?)
}

// puts in it wrong dir, and doen't have app version in name, but at least it zips the right content!
target ("zip-source" : "zips sources") {
    ant.delete(file: 'sources.zip')  // dont know how to add this to the clean cycle
