Question

我有build.gradle个文件：

...
jar {
   baseName 'dev-filename'
   manifest {
      attributes (
         'Class-Path': configurations.runtime.collect {it.getName() }.join(' ')
         'Main-Class': 'package.of.main.class'
      )
   }
}
...

属性文件src/main/resources/application.properties：

...
database.username=dev_user
database.password=dev_password
...

如何创建任务（dev和prod）来构建jar文件并更新属性文件中的值？

UPD1： 我接下来尝试了，但它不起作用：

...
jar {
   baseName 'dev-filename'
   manifest {
      attributes (
         'Class-Path': configurations.runtime.collect {it.getName() }.join(' ')
         'Main-Class': 'package.of.main.class'
      )
   }
   ant.propertyfile(file: 'application.properties') {
      entry(key: 'database.username', value: 'new_username')
      entry(key: 'database.password', value: 'new_password')
   }
}
...

Answer 1

在打包之前尝试处理您的资源。

processResources {
  filesMatching('*.properties') {
    filter( ReplaceTokens, tokens:['foo' : 'bar'])
  }
}

我解决了我的问题：

task jarProd(type: Jar) {
    doFirst {
        ant.property(file: "build/resource/main/config/application.properties") {
            entry(key: "database.username", value: "prod_user",
            entry(key: "database.password", value: "prod_password"
        }
    }
    baseName 'myapp'
    manifest {
      attributes (
         'Class-Path': configurations.runtime.collect {it.getName() }.join(' ')
         'Main-Class': 'package.of.main.class'
      )
   }
   with jar
}

task zipProd(dependsOn: jarProd, type: Zip) {
    baseName 'prod/myapp'
    from ('build/libs') {
        include("myapp.jar")
    }
    from configurations.runtime
}

task jarTest(type: Jar) {
    doFirst {
        ant.property(file: "build/resource/main/config/application.properties") {
            entry(key: "database.username", value: "test_user",
            entry(key: "database.password", value: "test_password"
        }
    }
    baseName 'myapp'
    manifest {
      attributes (
         'Class-Path': configurations.runtime.collect {it.getName() }.join(' ')
         'Main-Class': 'package.of.main.class'
      )
   }
   with jar
}

task zipTest(dependsOn: jarTest, type: Zip) {
    baseName 'test/myapp'
    from ('build/libs') {
        include("myapp.jar")
    }
    from configurations.runtime
}

task zip {
    dependsOn zipTest
    dependsOn zipProd
}

因此，我有2个相同的zip文件，其中包含不同的DB凭据
