Question

我想在网络应用程序上进行一些黑盒测试。因此，我想做以下事情： 1）解压缩tomcat以构建目录 2）解压缩Web应用程序以构建目录 3）从步骤1开始tomcat安装 4）做测试 5）停止tomcat

我迈出的第一步...

cargo {
    containerId = 'tomcat6x'
    port = 17388
    local {
        homeDir = file("$buildDir/install/apache-tomcat-6.0.30")
    }
}

task unpackTomcat << {
    file("$buildDir/install").mkdirs()
    ant.unzip(src: configurations.tomcat.files.iterator().next(), dest: "$buildDir/install")
}

task largeTests << {
    doFirst {
        unpackTomcat
    } 
    doLast {
        cargoStartLocal
    }
}
...

在执行largeTests任务时导致以下错误：

BUILD FAILED

Answer 1

<<是doLast的简写。因此largeTests从另一个操作添加了两个任务操作，这太晚了（必须在配置时添加操作）。不幸的是，错误信息不是很好。 :-)如果您在<<之后移除largeTests，则会在离开时出错。

另一项改进是对Copy使用unpackTomcat任务：

task unpackTomcat(type: Copy) {
    from zipTree(configurations.tomcat.singleFile)
    into "$buildDir/install" 
}

Answer 2

Peter是正确的，尽管你可能想要在解压缩后在shell脚本上设置正确的权限 - 如果你想让Gradle识别它已经执行了那个任务并跳过它，你应该考虑设置你的输入/输出同样。

这是我用来解压缩/复制新下载的tomcat副本并设置它的片段。

 /**
  * Expand the downloaded archive if it hasn't already been expanded
  */
 task explodeTomcatServer(dependsOn: downloadTomcat) {
     inputs.file file(tomcatZipFileLocation); 
     outputs.dir file(tomcatBaseName); 
     doLast {
         copy {
             from zipTree(tomcatZipFileLocation);
             into project.projectDir;
             include tomcatBaseName + '/bin/**';
             include tomcatBaseName + '/conf/**';
             include tomcatBaseName + '/lib/**';
             include tomcatBaseName + '/webapps/**';
             include tomcatBaseName + '/work/**';
         }
         // make sure that the shell scripts are set +x on linux / macs
         if (System.getProperty("os.name").toLowerCase().indexOf("win") < 0) {
             FileTree tree = fileTree(tomcatBaseName + '/bin').include('**/*.sh');
             tree.each { File file ->
                 logger.info('Setting +x permission on ' + file);
                 file.setExecutable(true);
             }
         }
     }
 }
