當通過exec-maven-plugin運行Java代碼時發生java.lang.reflect.InvocationTargetException

Question

我一直在爲此奮鬥了幾個小時。

我試圖運行與Maven的Java類和我收到以下錯誤

java.lang.reflect.InvocationTargetException

Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.5.0:java (default-cli) on project SupportUtilities: 
An exception occured while executing the Java class. null:

從日食從命令提示符

運行而不是在事情是我已經能夠成功地執行項目

這是我的pom.xml，我已經配置exec-maven-plugin v1.5.0

的問題是，我的代碼無法加載一個文件次位於我的資源文件夾中。

下面是對EnvHandler類的代碼，就在我com.services.util小號包

public Properties getProperty(String env, String mgmtSystem) throws IOException { 

     Properties prop = new Properties(); 
     InputStream propFile = null; 


     /* 
     * Loading based on OMS/IMS 
     */ 

     if("OMS".equalsIgnoreCase(mgmtSystem)) { 
      /* 
      * Loading the properties file based on environment qa/qa2/prod 
      */ 
      if("qa".equalsIgnoreCase(env)) { 

       propFile = EnvHandler.class.getResourceAsStream("/com/Services/agentsMonitor/OMS/Credentials_qa.properties"); //I have error here 
       System.out.println("PropFile->" + propFile.toString()); 
       prop.load(propFile); 
       return prop; 

      } 
      else if("qa2".equalsIgnoreCase(env)) { 

       propFile = EnvHandler.class.getResourceAsStream("/com/Services/agentsMonitor/OMS/Credentials_qa2.properties"); 
       prop.load(propFile); 
       return prop; 

      }else if("prod".equalsIgnoreCase(env)) { 

       propFile = EnvHandler.class.getResourceAsStream("/com/Services/agentsMonitor/OMS/Credentials_prod.properties"); 
       prop.load(propFile); 
       return prop; 

      } 
     } else if("IMS".equalsIgnoreCase(mgmtSystem)) { 
      /* 
      * Loading the properties file based on environment qa/qa2/prod 
      */ 
      if("qa".equalsIgnoreCase(env)) { 

       propFile = EnvHandler.class.getResourceAsStream("/com/Services/agentsMonitor/IMS/Credentials_qa.properties");  
       prop.load(propFile); 
       return prop; 

      } 
      else if("qa2".equalsIgnoreCase(env)) { 

       propFile = EnvHandler.class.getResourceAsStream("/com/Services/agentsMonitor/IMS/Credentials_qa2.properties"); 
       prop.load(propFile); 
       return prop; 

      }else if("prod".equalsIgnoreCase(env)) { 

       propFile = EnvHandler.class.getResourceAsStream("/com/Services/agentsMonitor/IMS/Credentials_prod.properties"); 
       prop.load(propFile); 
       return prop; 

      } 
     } 


     return null; 

} 

任何幫助，高度讚賞。

Answer 1

我一直在爲此而努力了好幾天，直到我發現這個錯誤，因爲在Windows中運行時，該reourceUrl不被視爲區分大小寫，但在unix機器上運行時，它被視爲大小寫敏感，所以資源已提到com/Services而不是/com/services

if("OMS".equalsIgnoreCase(mgmtSystem)) { 
     /* 
     * Loading the properties file based on environment qa/qa2/prod 
     */ 
     if("qa".equalsIgnoreCase(env)) { 

      propFile = EnvHandler.class.getResourceAsStream("/com/services/agentsMonitor/OMS/Credentials_qa.properties"); //I have error here 
      System.out.println("PropFile->" + propFile.toString()); 
      prop.load(propFile); 
      return prop; 

     } 
     else if("qa2".equalsIgnoreCase(env)) { 

      propFile = EnvHandler.class.getResourceAsStream("/com/services/agentsMonitor/OMS/Credentials_qa2.properties"); 
      prop.load(propFile); 
      return prop; 

     }else if("prod".equalsIgnoreCase(env)) { 

      propFile = EnvHandler.class.getResourceAsStream("/com/services/agentsMonitor/OMS/Credentials_prod.properties"); 
      prop.load(propFile); 
      return prop; 

     } 
    } else if("IMS".equalsIgnoreCase(mgmtSystem)) { 
     /* 
     * Loading the properties file based on environment qa/qa2/prod 
     */ 
     if("qa".equalsIgnoreCase(env)) { 

      propFile = EnvHandler.class.getResourceAsStream("/com/services/agentsMonitor/IMS/Credentials_qa.properties");  
      prop.load(propFile); 
      return prop; 

     } 
     else if("qa2".equalsIgnoreCase(env)) { 

      propFile = EnvHandler.class.getResourceAsStream("/com/services/agentsMonitor/IMS/Credentials_qa2.properties"); 
      prop.load(propFile); 
      return prop; 

     }else if("prod".equalsIgnoreCase(env)) { 

      propFile = EnvHandler.class.getResourceAsStream("/com/services/agentsMonitor/IMS/Credentials_prod.properties"); 
      prop.load(propFile); 
      return prop; 

     } 
    }
