我正在构建一个Android项目，其中包含一些使用Proguard的buildType。在建造期间，我看到了来自Proguard的大量警告。因为这些警告是为我正在使用的第三方类生成的，所以我试图在我的'proguard-rules.pro'文件中使用-dontwarn标志和-dontnote标志，这样我将来就不会看到错误输出。但是，我看到的问题是，即使我将这些标志添加到我的.pro文件并在build.gradle中指定.pro文件，我仍然会在构建项目时看到警告输出。
以下是build.gradle文件的相关部分：
buildTypes {
debug {
applicationIdSuffix ".debug"
}
unitTest {
applicationIdSuffix ".unittest"
minifyEnabled true
// proguardFiles getDefaultProguardFile("proguard-android.txt")
proguardFile('proguard-rules.pro')
}
automation {
applicationIdSuffix ".automation"
minifyEnabled true
// proguardFile getDefaultProguardFile('proguard-android.txt')
proguardFile('proguard-rules.pro')
}
internal {
applicationIdSuffix ".internal"
minifyEnabled true
// proguardFiles getDefaultProguardFile('proguard-android.txt')
proguardFile('proguard-rules.pro')
}
release {
minifyEnabled true
// proguardFiles getDefaultProguardFile("proguard-android.txt")
proguardFile("proguard-rules.pro")
}
}
这是我的proguard-rules.pro文件：
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in /usr/local/Cellar/android-sdk/24.3.3/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.
#
# For more details, see
# http://developer.android.com/guide/developing/tools/proguard.html
# Add any project specific keep options here:
# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
# public *;
#}
# Disabling obfuscation is useful if you collect stack traces from production crashes
# (unless you are using a system that supports de-obfuscate the stack traces).
-dontobfuscate
# React Native
# Keep our interfaces so they can be used by other ProGuard rules.
# See http://sourceforge.net/p/proguard/bugs/466/

请注意，proguard-rules.pro文件位于引用它的build.gradle文件旁边的project / app /目录中。

为什么在应用proguard-rules.pro文件时错误消息不会被压缩？
