我在构建应用程序的发布版本时遇到了实际困难。
这是我在运行./gradlew assembleRelease --stacktrace --debug
在Android Studio中它会吐出同样的东西而且我已经抓了网但还没有找到解决方案。

我面临完全相同的问题，我已经能够构建已签名的apk，只是在发布版本中禁用minifyEnable：
minifyEnabled false
<强>更新
我已经能够解决问题，将以下内容添加到proguard配置（proguard-rules.pro文件）中：
-dontwarn javax.naming.**
这将在编译时清除/跳过所有警告，并解决我身边的问题。

为我解决问题的Proguard
以下proguard配置文件最终为我做了诀窍。
# This is a configuration file for ProGuard.
# http://proguard.sourceforge.net/index.html#manual/usage.html
# Optimizations: If you don't want to optimize, use the
# proguard-android.txt configuration file instead of this one, which
# turns off the optimization flags. Adding optimization introduces
# certain risks, since for example not all optimizations performed by
# ProGuard works on all versions of Dalvik. The following flags turn
# off various optimizations known to have issues, but the list may not
# be complete or up to date. (The "arithmetic" optimization can be
# used if you are only targeting Android 2.0 or later.) Make sure you
# test thoroughly if you go this route.
-optimizations !code/simplification/arithmetic,!code/simplification/cast,!field/*,!class/merging/*
-optimizationpasses 5
-allowaccessmodification
-dontpreverify
# The remainder of this file is identical to the non-optimized version
# of the Proguard configuration file (except that the other file has
# flags to turn off optimization).

确保输入jar确实存在。自问题
proguard.ConfigurationChecker.check(ConfigurationChecker.java:64)
task proguard(type: ProGuardTask) {
injars inputJar
outjars outPutJar
...
}
如果 inputJar 不存在，那么 ConfigurationChecker 会抱怨。
我查看了代码并发现 ProGuardTask 将jar添加到classpath（如果它们确实存在或者它们是输出）。在http://grepcode.com/file/repo1.maven.org/maven2/net.sf.proguard/proguard-gradle/5.2.1/proguard/gradle/ProGuardTask.java?av=f#1180
检查ProGuardTask.java的第1180行while (fileIterator.hasNext())
{
File file = (File)fileIterator.next();
if (output || file.exists())
{
//skip
classPath.add(classPathEntry);
}
}
