Gradle Manifest.MF

Question

我正在做的是將我的項目中預先創建的manifest.mf文件與gradle中jar任務的動態創建的清單文件結合起來。

有沒有辦法做到這一點？目前我正在生成我的清單文件完全： -

jar.doFirst { 
    manifest { 
     def requiredProjects = '' 
     configurations.compile.getAllDependencies().withType(ProjectDependency).each {dep-> 
      def dependantProjects = dep.getDependencyProject() 
      def projects = project(dependantProjects.path).libsDir.list().findAll{it.endsWith('.jar')} 
      projects.removeAll(projects.findAll{it.endsWith('test.jar')}) 
      def requiredProject = projects.join(' ') 
      requiredProjects += requiredProject.replaceAll(/ /,'%20') + ' ' 
      logger.info 'Required Project: ' + requiredProject 
     } 
     logger.info 'Required requiredProjects: ' + requiredProjects 

     def compileFiles = configurations.compile.files{ it instanceof ExternalDependency }.collect { 
      File file = it 
      "lib/${file.name}" 
     }.join(' ') 

     def manifestPath = requiredProjects + compileFiles 
     logger.info 'Manifest: '+ manifestPath 
     attributes 'Class-Path': manifestPath 
     attributes 'Build-date': new Date(); 
     attributes 'Application-Version': project.version 
    } 
} 

我知道我會有一個/META-INF/MANIFEST.MF文件。

最初我使用的是Gradle的OSGI插件，但是這似乎忽略了清單文件併產生了巨大的混亂。

我看着這個頗有幾分，感謝卡羅我發現下面的代碼可以讓我看現有的MANIFEST.MF： -

jar { 
     onlyIf { !compileJava.source.empty } 
     manifest { 
      // benutze das im Projekt vorliegende File, falls vorhanden: 
      def manif = "${projectDir}/META-INF/MANIFEST.MF" 
      if (new File(manif).exists()) {     
       from (manif) { 
        eachEntry { details ->       
         if (details.key == 'Bundle-Vendor') { 
                details.value = 'xyz GmbH' 
         } 
        } 
       }          
      } 
      else { 
       logger.info(project.name + " doesn't have a META-INF/MANIFEST.MF.") 
       manifest.attributes provider: xyz GmbH' 
       manifest.attributes project: project.name 
       manifest.attributes Build: new Date() 
      } 
     } 
     // copy if we have these:   
     from file ('plugin.xml')    
     from file ('plugin.properties')  
     into ('icons') { // if any ... 
      from fileTree('icons') 
     } 
    }

最後，我已經成功地得到我想要使用下面的代碼： -

jar.doFirst { 
    manifest { 
     def manifestFile = "${projectDir}/META-INF/MANIFEST.MF" 
     if (new File(manifestFile).exists()) 
      from (manifestFile) 
     def requiredProjects = '' 
     configurations.compile.getAllDependencies().withType(ProjectDependency).each {dep-> 
      def dependantProjects = dep.getDependencyProject() 
      def projects = project(dependantProjects.path).libsDir.list().findAll{it.endsWith('.jar')} 
      projects.removeAll(projects.findAll{it.endsWith('test.jar')}) 
      def requiredProject = projects.join(' ') 
      requiredProjects += requiredProject.replaceAll(/ /,'%20') + ' ' 
      logger.info 'Required Project: ' + requiredProject 
     } 
     logger.info 'Required requiredProjects: ' + requiredProjects 

     def compileFiles = configurations.compile.files{ it instanceof ExternalDependency }.collect { 
      File file = it 
      "lib/${file.name}" 
     }.join(' ') 

     def manifestPath = requiredProjects + compileFiles 
     logger.info 'Manifest: '+ manifestPath 
     attributes 'Class-Path': manifestPath 
     attributes 'Build-date': new Date(); 
     attributes 'Application-Version': project.version 
    } 
} 

重要的是行 -

def manifestFile = "${projectDir}/META-INF/MANIFEST.MF" 
if (new File(manifestFile).exists()) 
    from (manifestFile) 

這讓我繼承任何現有的/META-INF/MANIFEST.MF文件，並且還包括由gradle動態管理的類路徑依賴關係。
