gradle中的任务在编译前包含java类

Question

我需要创建Gradle任务，它可以在Gradle构建之前替换.java文件。分级在.war文件中构建包应用程序。我需要在构建后替换字节码。我试过sourceSets Gradle任务，但它只能排除文件。

sourceSets {
        main {
            java {
                exclude 'com/myapp/example/resource/impl/ResourceBundleImpl.java'
            }
        }
    }

但我需要在同一地方也包括文件。我怎么能和Gradle在一起？

The directory to  file that I need to exclude: com/myapp/example/resource/impl/ResourceBundleImpl.java
The directory to file that I need to include: src/main/webapp/WEB-INF/my/ResourceBundleImpl.java

  task prepareSources(type: Copy) {
        from('src/main/webapp/WEB-INF/my')
        into('build/classes/java/main/com/myapp/example/resource/impl')com/myapp/example
    }

// Prepare sources, before compile
    compileJava {
        dependsOn prepareSources
    }

sourceSets {
    main {
        java {
            srcDir "$projectDir"

            exclude 'com/medtronic/diabetes/carelink/rbps/resource/impl/ResourceBundleImpl.java'

            include 'src/main/webapp/WEB-INF/my/ResourceBundleImpl.java'
        }
    }

我将需要替换的类放在一起，并为其中一个类添加后缀，并在编译期间替换这个后缀：

   sourceSets {
        main {
            java {
                srcDirs = ["$buildDir\\generated-src"]
            }
        }
    }

    task copySourceSet(type: Copy) {

        println 'Change java class in patient-svc-war'

        from "$rootDir\\patient-svc-war\\src\\main\\java"
        into "$buildDir\\generated-src"

        from file("$rootDir\\patient-svc-war\\**_suffix.java")
        into "$buildDir\\generated-src"
        rename { String fileName ->
            fileName.replace("_suffix", "")
        }

        filter { line -> line.replaceAll('_suffix', '')}
    }

    compileJava.source "$buildDir\\generated-src"

    compileJava {
        dependsOn copySourceSet
    }

    compileJava.doLast {
        delete "$buildDir\\generated-src"
    }
