proguard-android-optimize build failed

Question

i am trying to disable all logs

-assumenosideeffects class android.util.Log {

public static *** v(...);
public static *** i(...);
public static *** w(...);
public static *** d(...);
public static *** e(...);

}

 -assumenosideeffects class android.util.Log { *; }

but when i set

          proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'

build faild error

    UNEXPECTED TOP-LEVEL EXCEPTION:
Error:java.lang.InterruptedException: Too many errors
at com.android.dx.command.dexer.Main.processAllFiles(Main.java:600)
... 4 more
Error:Execution failed for task ':app:transformClassesWithDexForDebug'.

com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Library/Java/JavaVirtualMachines/jdk1.8.0_66.jdk/Contents/Home/bin/java'' finished with non-zero exit value 2

with this proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' its build but logs are visible

The recommended solution is to recompile the class from source, using an up-to-date compiler and without specifying any "-target" type options. The consequence of ignoring this warning is that reflective operations on this class will incorrectly indicate that it is not an inner class.

Uncaught translation error: com.android.dx.cf.code.SimException: local variable type mismatch: attempt to set or access a value of type java.lang.Object using a local variable of type int. This is symptomatic of .class transformation tools that ignore local variable information.

Please use the following proguard for the reference as during optimizations, native methods need to keep as it is.

-dontusemixedcaseclassnames
-optimizationpasses 5
-allowaccessmodification
-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.preference.Preference
-keep public class * extends android.support.v4.app.Fragment
-keep public class * extends android.app.Fragment
# For native methods, see http://proguard.sourceforge.net/manual/examples.html#native
-keepclasseswithmembernames class * {
 native <methods>;
}
-keep public class * extends android.view.View {
 public <init>(android.content.Context);
 public <init>(android.content.Context, android.util.AttributeSet);
 public <init>(android.content.Context, android.util.AttributeSet, int);
 public void set*(...);
}
-keepclasseswithmembers class * {
 public <init>(android.content.Context, android.util.AttributeSet);
}
-keepclasseswithmembers class * {
 public <init>(android.content.Context, android.util.AttributeSet, int);
}
-keepclassmembers class * extends android.app.Activity {
 public void *(android.view.View);
}
# For enumeration classes, see http://proguard.sourceforge.net/manual/examples.html#enumerations
-keepclassmembers enum * {
 public static **[] values();
 public static ** valueOf(java.lang.String);
}
-keep class * implements android.os.Parcelable {
 public static final android.os.Parcelable$Creator *;
}

hope this helps.
