起因於我用了 Spring，然後包 jar 沒問題，都有包進去，但是執行時出錯。
Exception in thread "main" org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/context] Offending resource: class path resource [spring-app.xml]說是找不到 NamespaceHandler，這是什麼鬼東西啊。
我在 Eclipse 裡執行都沒問題啊，包成 jar 來執行就丟出這個錯誤來。
抓破頭皮後終於找到解答。
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>1.7.1</version>

除了原本就有的 org.apache.maven.plugins.shade.resource.ManifestResourceTransformer，還要加上兩個 transformer，使用同一個 implementation，為 org.apache.maven.plugins.shade.resource.AppendingTransformer。沒加這兩個 transformer，還是會產生 META-INF/spring.handlers 與 META-INF/spring.schemas，但是加了之後，這兩個檔案的內容變多了。
