我对 Gradle 生命周期有一个基本的询问。我的项目是一个多模块项目。

我注意到以下命令:

./gradlew clean bignibou-server:run

不等于运行以下两个命令按顺序运行:

./gradlew clean

./gradlew bignibou-server:run

bignibou-server是我的模块之一。

第一个命令的输出导致以下两个命令的输出不同。

有人可以解释为什么这可能指向相关文档吗？

biên tập :在第一种情况下，一个生成的源输出被删除，而在第二种情况下它没有被删除。怎么会这样？

编辑 3 : 被第一个命令而不是第二个命令删除的文件夹如下(来自 bignibou-common 模块):

build/generated-mail-templates

编辑 4 : 我注意到在注释掉 output.dir(... 之后调用(见下文)， build/generated-mail-templates没有被删除，但不幸的是模板不包含在类路径中......

   sourceSets {
      chủ yếu {
        ext.originalJavaSrcDirs = java.srcDirs
        java.srcDir "build/generated-sources/mapstruct/main"
        //output.dir("build/generated-mail-templates")

task processMailTemplates {

    dependsOn npmInstall

    def templateSrcDir = "src/main/templates/mail/"
    def templateDestDir = "build/generated-mail-templates/META-INF/templates/mail/"

    mkdir templateDestDir

    def templateNames = []

    fileTree(dir: templateSrcDir, include: '**/*.html').visit {
        FileVisitDetails details -> templateNames << details.file.name
    }

    templateNames.each { templateName -> inlineCss(templateSrcDir + templateName, templateDestDir + templateName) }

    outputs.upToDateWhen { false }
}

无论您要求 gradle 执行什么任务，所有这些代码都在配置阶段执行。它应该在执行阶段执行:

task processMailTemplates {
    description "Processes mail templates"
    dependsOn npmInstall

    outputs.upToDateWhen { false }

    doLast {
        def templateSrcDir = "src/main/templates/mail/"
        def templateDestDir = "build/generated-mail-templates/META-INF/templates/mail/"

        mkdir templateDestDir

        def templateNames = []

        fileTree(dir: templateSrcDir, include: '**/*.html').visit {
            FileVisitDetails details -> templateNames << details.file.name
        }

        templateNames.each { templateName -> inlineCss(templateSrcDir + templateName, templateDestDir + templateName) }
    }
}
