2.0.3-rc02 版本无法通过构建

[XuanJiAndroid]

运行背景：
jdk 1.8.0
gradle 6.1.1
AGP 4.0

在 > Task :app:dexBuilderDebug 阶段会大量有报错，类型信息如下：

AGPBI: {"kind":"error","text":"NullPointerException during IR Conversion","sources":[{"file":"/Users/ram/workspace/workDir/xx-android/app/build/intermediates/transforms/rheaTrace/debug/81.jar"}],"tool":"D8"}

app目录下的gradle配置如下：

rheaTrace {

    compilation {
        //为减少 APK 体积, 你可以为 App 中需要跟踪的方法设置 id 以此来跟踪此自定义事件, 默认值 false。
//        traceWithMethodID = false
        //该文件配置决定哪些方法您不希望跟踪, 默认值 null。
        traceFilterFilePath = "${project.rootDir}/rhea-trace/traceFilter.txt"
        //用特指定方法 id 来设置自定义事件名称, 默认值 null。
//        applyMethodMappingFilePath = "${project.rootDir}/rhea-trace/keep-method-id.txt"
        needPackageWithMethodMap = true
    }

    runtime {
        //仅在主线程抓取跟踪事件, 默认值 false。
        mainThreadOnly true
        //在 App 启动之初开始抓取跟踪事件, 默认值 true。
        startWhenAppLaunch true
        //指定内存存储 atrace 数据 ring buffer 的大小。
        atraceBufferSize "500000"
    }
}

traceFilter.txt 文件内容如下：

-blockpackage com/google
-blockpackage android/support
-blockpackage androidx/

麻烦提供一下详细的构建失败日志吧，如果方便的话也提供下错误中涉及的 build/intermediates/transforms/rheaTrace/debug/81.jar jar 包。

为什么我配置多个屏蔽项目，只有最后一个有用？

有8个类似下发的报错
org.gradle.tooling.BuildException: Failed to process: C:\Users\fionn.zhang\AndroidStudioProjects\n1904\app\build\intermediates\transforms\rheaTrace\overseaFour\debug\29.jar

我发现windows下创建并写入的traceFilter.txt，换行结尾存在”\r”，找到对应的解析代码FileUtils类，方法parseTraceFilterFile

rhea-build/rhea-build-common/src/main/java/com/bytedance/rheatrace/common/utils/FileUtil.kt

    private fun parseTraceFilterFile(processor: MappingCollector) {
        // ...
        val methodKeepArray =
            methodKeepStr.trim { it <= ' ' }.replace("/", ".").split("\n").toTypedArray()
        val iterator = methodKeepArray.iterator()
        loop@ while (iterator.hasNext()) {
            val item = iterator.next()
            when {
		            // ...
                item.startsWith("-blockpackage ") -> {
                    val blockPackageString = item.replace("-blockpackage ", "")
                    blockPackages.add(blockPackageString)
                }
                // ...
            }
        }
        RheaLog.i(TAG, " allow packages: $allowPackages, block packages: $blockPackages")
    }

针对读取的结果字符串split("\n")，只处理了linux环境下文件换行符，对于window的\r没有处理，导致解析只保留了最后一行的结果
测试代码：

    @Test
    fun readFileAsString() {
        val filePath = "D:\\study\\android\\KotlinStart/trace-filter/testFileFilter.txt"
        if (filePath == null) {
            return
        }
        if (!File(filePath).exists()) {
            return
        }
        val fileData = StringBuffer()
        var fileReader: Reader? = null
        var inputStream: InputStream? = null
        try {
            inputStream = FileInputStream(filePath)
            fileReader = InputStreamReader(inputStream, "UTF-8")
            val buf = CharArray(16384)
            var numRead: Int
            while (fileReader.read(buf).also { numRead = it } != -1) {
                val readData = String(buf, 0, numRead)
                fileData.append(readData)
            }
        } catch (e: Exception) {
            e.printStackTrace()
            return
        } finally {
            try {
                closeQuietly(
                    fileReader
                )
                closeQuietly(
                    inputStream
                )
            } catch (e: Exception) {
                e.printStackTrace()
            }
        }
        print("读取文件结果：${fileData.toString()}")
        val methodKeepArray =
            fileData.toString().trim { it <= ' ' }.trimEnd().replace("/", ".").split("\n").toTypedArray()
        val iterator = methodKeepArray.iterator()
        val blockPackages: MutableList<String> = mutableListOf<String>()
        loop@ while (iterator.hasNext()) {
            val item = iterator.next()
            when {
                item.startsWith("-blockpackage ") -> {
                    val blockPackageString = item.replace("-blockpackage ", "")
                    blockPackages.add(blockPackageString)
                }
            }
        }
        blockPackages.forEach {
            print("输出: $it  ")
        }
        return
    }

testFileFilter.txt

-blockpackage com/android/test
-blockpackage com/android/text
-blockpackage com/android/input

输出结果如下：

读取文件结果：-blockpackage com/android/test
-blockpackage com/android/text
  输出: com.android.input  

如果将split符号再做修改

val methodKeepArray =
            fileData.toString().trim { it <= ' ' }.trimEnd().replace("/", ".").split("\r\n").toTypedArray()

则输出所有-blockpackage，符合txt的预期内容

读取文件结果：-blockpackage com/android/test
-blockpackage com/android/text
-blockpackage com/android/input输出: com.android.test  输出: com.android.text  输出: com.android.input

因此针对window的文件可以参考如下方法去除\r

还有一种方式：就是在linux上编写这个traceFilter.txt然后拷贝到window上
