Spring boot: невозможно открыть вложенную запись 'WEB-INF/lib-обеспечен /ecj-3.12.3.jar'

Question

Я пытаюсь запутать приложение весенней загрузки. Пакет: война

Я следовал подходу сценария муравья с Yguard

Ссылка: http://codeaweso.me/2009/02/obfuscating-a-webapp-war-file-with-yguard-and-ant/

Структура проекта:

main.war

• a.jar

• b.jar

и еще много сторонних зависимостей.

Я вижу, что мы успешно запутали требуемый файл jar зависимостей сторонних производителей.

Кроме того, мы сохранили другие библиотеки без сбоев и без сжатия, но некоторые из них, как они сжимаются.

Исключение, которое мы получаем

java -jar webapp_obf.war

Любое предположение, почему мы могли бы исключение сжатия.

Answer 1

Когда вы пытаетесь построить банку, предоставьте только следующие опции.

Maven-плагин сборки

 <archive> 
<compress>false</compress>
 </archive>

Также мы можем предоставить то же самое в весенне-загрузочном плагине maven.
