WebLogic - Jar在那里，但NoClassDefFoundError：org / apache / commons / io / IOUtils

将ear（myapp.ear）部署到weblogic 12.1.3时出现部署错误。错误：

  

NoClassDefFoundError：org / apache / commons / io / IOUtils

注意：

  1. 编译好：mvn clean; mvn install
  2. EAR有 APP-INF / lib / commons-io-2.4.jar 有哪个类
  3. 想到也许是一个罐子冲突。 weblogic有2个jars w / same package.class（wlserver / modules / com.bea.core.apache.commons.io_1.2.0.0_1-4.jar＆amp; wlserver / modules / features / weblogic.server.merged.jar）但是......那些不在课堂上
  4. 再次尝试将jar添加到app（scope = provided - pom.xml）但错误相同

    5. 实际错误：

请参阅<prefer-web-inf-classes>和<prefer-application-packages>。

http://docs.oracle.com/cd/E24329_01/web.1211/e21049/weblogic_xml.htm#WBAPP602

类似的问题如下：

How to set order of jars in WebLogic?

我会首先尝试<prefer-application-packages>解决方案。

然而，NoClassDef意味着该字体确实找不到。你编译它但它不再在类路径上（所以也检查你的耳朵的结构）。请参阅：What causes and what are the differences between NoClassDefFoundError and ClassNotFoundException?
