gradle tar任务未执行

我正在为一个非java项目编写一个Gradle构建，用于将现有目录和tar存档组装到.tar.gz中。如果我使用如下定义，则tar任务将跳过：

task archive(dependsOn: 'initArchive',type: Tar) << {
    baseName = project.Name
    destinationDir = new File(project.buildDir.path+'/installer')
    compression = Compression.GZIP
    from (archiveDir)
    doLast{
        checksum(archivePath)
    }
}

当我尝试使用tar任务作为方法时，它失败了，因为找不到方法

task archive(dependsOn: 'initArchive') << {
    tar{
    baseName = project.Name
    destinationDir = new File(project.buildDir.path+'/installer')
    compression = Compression.GZIP
    from (archiveDir)
    doLast{
        checksum(archivePath)
    }
    }
}

如果不是，如何确保我的构建在使用上述第一种形式时不会“跳过tar”任务。

您已经陷入了在执行阶段而不是配置阶段配置任务的经典错误。解决方法是删除

我遇到了一个有趣的情况，在tar任务中使用doLast{}时，我遇到了这个问题

这是因为一个多项目构建：

build.gradle
--> sub-project
    --> build.gradle

在这种情况下，如果您尝试在主生成文件中包含一个引用该
项目（“：子项目”）
使用的内容的
tar
或
copy
任务，则开发人员会尝试将其包装在doLast中

例如，主build.gradle文件具有：

  task distTar(type: Tar, dependsOn: "buildDist") {
    description "Package ProjName into a Tar file"
    group "Build"
    baseName = 'outbasename'
    archiveName = baseName + '.tar.gz'
    compression = Compression.GZIP
    destinationDir = file(project(":packaging").buildDir.path)
    extension = 'tar.gz'
    into('outdir') {
      from project(":sub-project").war
    }
  }

所以他们得到了一个错误，
project（“：subproject”）。war
不存在。因此，为了解决这个问题，有人把任务和错误放在一边。糟糕

  task distTar(type: Tar, dependsOn: "buildDist") {
    doLast { // <-- BAD!!
      description "Package ProjName into a Tar file"
      group "Build"
      baseName = 'outbasename'
      archiveName = baseName + '.tar.gz'
      compression = Compression.GZIP
      destinationDir = file(project(":packaging").buildDir.path)
      extension = 'tar.gz'
      into('outdir') {
        from project(":sub-project").war
      }
    }
  }

task distTar（类型：Tar，dependsOn:“buildDist”）{
doLast{//不可思议？我也遇到了这个问题，没有犯那个错误。生成路径的代码创建了一个不存在的路径（因此，没有源文件）。因此，当出现奇怪情况时，记录路径并检查它，如果它不是配置-执行问题注意，左移位运算符当前已被弃用，将在未来版本中删除：
  task distTar(type: Tar, dependsOn: "buildDist") {
    description "Package ProjName into a Tar file"
    group "Build"
    baseName = 'outbasename'
    archiveName = baseName + '.tar.gz'
    compression = Compression.GZIP
    destinationDir = file(project(":packaging").buildDir.path)
    extension = 'tar.gz'
    into('outdir') {
      from project(":sub-project").war
    }
  }

  task distTar(type: Tar, dependsOn: "buildDist") {
    doLast { // <-- BAD!!
      description "Package ProjName into a Tar file"
      group "Build"
      baseName = 'outbasename'
      archiveName = baseName + '.tar.gz'
      compression = Compression.GZIP
      destinationDir = file(project(":packaging").buildDir.path)
      extension = 'tar.gz'
      into('outdir') {
        from project(":sub-project").war
      }
    }
  }
