我有一個項目，其中Main-Method-class類的「Bootstrap.class」位於src/test文件夾中。所以我用<classpathScope>test</classpathScope> 能夠執行Maven exec plugin-如何在classpathscope = test時從main/java導入類
mvn exec:java
我的問題：我得到一個「java.lang.IllegalArgumentException異常：未知實體：」造成I'm進口某些種類的，這是位於主/ JAVA 。關於如何解決這個問題的任何想法？
這是我的雙響炮：

看起來像hibernate配置錯誤 - 見[該相關（http://stackoverflow.com/questions/7887481/how-to-get-rid-of-java-lang- illegalargumentexception-unknown-entity-while-run）SO問題 – Raghuram 2012-04-04 11:41:45
這也是我的第一個想法。但服務器和我的應用程序開始沒有任何問題。當我試圖將類「Bootstrap」（位於src/test中，並且包含一個main方法）作爲java應用程序運行時，纔會引發上述異常。 – slowessam 2012-04-04 12:22:15
像@Raghuram說的，這看起來像一個Hibernate的conf問題 - 我的猜測是你沒有定義xml映射或應用java註釋到'eu.paedrtx.register.server.domain.PaymentDetails'類 – 2012-04-07 20:49:41
