proguard+springboot plugin -> no classes in jar - proguard

Question

I have to obfuscate lib and application. Lib - simple lib with two classes. Obfuscation done well. Application(with obfuscated lib in dependencies) builded with springboot plugin, works well.
When I try to obfuscate application jar I have got jar without *.classes of my app.
here is proguard conf:
-verbose
-dontwarn
-dontoptimize
-dontpreverify
-printmapping out.map
-keepattributes Exceptions,InnerClasses,Signature,Deprecated,SourceFile,LineNumberTable,*Annotation*,EnclosingMethod
-keepdirectories
-keep class org.springframework.******* { *;}
-keep public class * extends RequestEntity { *;}
-keep public class * extends ResponseEntity { *;}
-keepclassmembers,allowoptimization enum * {
public static **[] values();
public static ** valueOf(java.lang.String);
}
-keepnames class * implements java.io.Serializable {*; }
-keepclasseswithmembers public class * {
public static void main(java.lang.String[]);
}
classes:
public class TestEntity {
private Integer fieldInt;
private String fieldStr
--cut--- (set* get*)
public class TestActions {
private TestEntity entity;
Gson gson = new Gson();
--cut---(set* get*)
import my.act.TestActions;
public class App {
public static void main(String[] args) {
TestActions testActions=new TestActions();
testActions.doPrintEntity();
}
}
out.map:
my.App -> my.App:
6:6:void <init>() -> <init>
8:10:void main(java.lang.String[]) -> main
org.springframework.boot.loader.ExecutableArchiveLauncher -> org.springframework.boot.loader.ExecutableArchiveLauncher:
org.springframework.boot.loader.archive.Archive archive -> archive
37:44:void <init>() -> <init>
--cut---
rows about spring...
and I have got test_app1.jar without my.App, only empty folder:
test_app1.jar\BOOT-INF\classes\my\
Any ideas? Help please...

If you use proguard maven plugin for a springboot application. Don't forget to add spring package plugin as well.
