spring - java maven proguard plugin obfuscator -


i'm trying obfuscate java application i'm developing, , decided use proguard maven plugin it.

i solve few problems following proguard configuration:

# don't obfuscate or remove entry point -keep public class com.appspot.main {     public static void main(java.lang.string[]); }  # supress warnings javax.servlet -dontwarn javax.servlet.**  -keepattributes *annotation*,signature,innerclasses

now i'm having following error:

 [proguard] note: org.springframework.core.io.support.pathmatchingresourcepatternresolver accesses method 'resolve(java.net.url)' dynamically  [proguard] note: there 18 unresolved dynamic references classes or interfaces.  [proguard]       should check if need specify additional program jars.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
