Android Studio - java.io.IOException:无法生成 v1 签名
在将我的 Android Studio 更新到 3.0 Canary 4 之后的所有新版本后，我收到此错误.(我使用的是 v3.0，因为它速度更快，并且无需为 Kotlin 进行 jack.)
I get this error after updating my Android Studio to all new versions after 3.0 Canary 4. (I am using v3.0 cause it is much faster and there is no need to jack for Kotlin.)
构建流程似乎存在问题，无法为调试版和发布版生成或签署我的 APK 文件.
It looks like there is an issue with build flow that it cannot generate or sign my APK file for both debug and release version.
我也试过删除我的debug.keystore，重新启动AndroidStudio和系统(！！！)但没有解决.
I also tried deleting my debug.keystore, restarting AndroidStudio and system(!!!) but it didn't solve.
这是一个完整的 Gradle 日志:
Here is a full Gradle log:

使用 gradle assemble --stacktrace 命令进行更多调查后，我发现问题出在 APK 压缩过程中:
After more investigation using gradle assemble --stacktrace command I found that the issue is with APK zipping process:
错误:org.gradle.tooling.BuildException:无法生成 v1签名错误:java.io.IOException:无法生成 v1 签名错误:com.android.apksig.apk.ApkFormatException:不支持的字符0x0d 在 ZIP 条目名称资产/图标?"
Error:org.gradle.tooling.BuildException: Failed to generate v1 signature Error:java.io.IOException: Failed to generate v1 signature Error:com.android.apksig.apk.ApkFormatException: Unsupported character 0x0d in ZIP entry name "assets/Icon?"
有一个名为图标?"的文件.在我的项目中，这是一个指示文件夹图标的 MacOS 文件，其中包含 CR, LF 字符.
There was a file named "Icon?" in my project which is a MacOS file that indicates folder's icon and it contains CR, LF characters inside.
我删除了文件，现在一切正常.
I deleted the file and now everything is working fine.
这个问题出现在 Android Studio Canary 4 之后的所有版本中，我在这个线程上向 Android Studio 团队报告了这个问题 https://issuetracker.google.com/issues/63885809
This issue showed up in all versions after Android Studio Canary 4 and I report the issue to Android Studio team on this thread https://issuetracker.google.com/issues/63885809
他们提到:
3.0 Canary 4 大约是我们添加不支持的字符"检查的时间，所以这就是从那个版本开始它发生的原因.
3.0 Canary 4 is about the time we added that "Unsupported character" check, so that's why it happens from that version forward.
他们正在调查更多以解决这个问题，我希望这个答案可以帮助其他人不要浪费一个月不更新他们的 Android Studio.:)
They are investigating more to solve this issue and I hope this answer helps others not to waste one month not updating their Android Studio. :)
