android app构建时排除指定类

news2025/1/4 5:51:39

背景：因为某些需求，需要将android appA打包为aar供其他工程使用，但是有些class有冲突，只能将appA中的类排除。

具体做法：

在build.gradle中排除指定的类,

// build.gradle顶部引入import java.text.SimpleDateFormat

// 创建一个时间格式化器
def dateFormat = new SimpleDateFormat('yyyy-MM-dd HH:mm:ss')

afterEvaluate {
    // 找到负责打包 AAR 的任务
    tasks.matching { it.name == 'compileReleaseJavaWithJavac' }.configureEach { bundleAarTask ->
        def arrFile = 'build/outputs/aar/sdk_module_a-release.aar'
        if (!file(arrFile).exists()) {
            println "${dateFormat.format(new Date())} - 12file of sdk_module_a does not exist."
        } else {
            println "${dateFormat.format(new Date())} - 12file of sdk_module_a does exist."
        }

        // 在打包 AAR 前执行删除类文件的任务
        println "${dateFormat.format(new Date())} - 18compileReleaseJavaWithJavac delete class."

        // 打印日志，表明即将开始打包 AAR
        bundleAarTask.doFirst {
            println "${dateFormat.format(new Date())} - 18Starting to compileReleaseJavaWithJavac..."
        }

        bundleAarTask.doLast {
            println "${dateFormat.format(new Date())} - 18last to compileReleaseJavaWithJavac..."
            def baseDir = 'build/intermediates/javac/release/classes/com/x/y/navi'
            def classesToDelete = [
                    "$baseDir/NaviCsv.class",
                    "$baseDir/NaviCsv\$1.class",
                    "$baseDir/NaviCsv\$Zxc.class"
            ]

            classesToDelete.each { classFile ->
                if (file(classFile).exists()) {
                    println "${dateFormat.format(new Date())} - 18-02 ${classFile} exist"
                } else {
                    println "${dateFormat.format(new Date())} - 18-02 ${classFile} file not exist"
                }
            }

            // 删除操作
            delete classesToDelete

            classesToDelete.each { classFile ->
                if (file(classFile).exists()) {
                    println "${dateFormat.format(new Date())} - 18-03Failed to delete ${classFile}"
                } else {
                    println "${dateFormat.format(new Date())} - 18-03delete ${classFile} file ok"
                }
            }
        }
    }
}
