我試圖生成pojos或與休眠工具映射時收到noclassdeffounderror

Question

我試圖從我的數據庫中生成pojos，但我在eclipse indigo 3.7.2與hibernate工具3.4插件安裝時得到以下錯誤（s）和休眠3.6.10庫（他們似乎是所有）在我的構建路徑

短版：

org.hibernate.console.HibernateConsoleRuntimeException: Received a NoClassDefFoundError, probably the console configuration classpath is incomplete or contains conflicting versions of the same class 
Received a NoClassDefFoundError, probably the console configuration classpath is incomplete or contains conflicting versions of the same class 
    java.lang.NoClassDefFoundError: Could not initialize class org.hibernate.cfg.reveng.OverrideRepository 
    Could not initialize class org.hibernate.cfg.reveng.OverrideRepository 
    java.lang.NoClassDefFoundError: Could not initialize class org.hibernate.cfg.reveng.OverrideRepository 
    Could not initialize class org.hibernate.cfg.reveng.OverrideRepository 

MY從項目構建路徑是（按順序，如果該事項）罐：

• hibernate-distribution-3.6.10.Final \ hibernate3.jar
• hibernate-distribution-3.6.10.Final \ lib \ required \ antlr-2.7.6.jar
• hibernate-distribution-3.6.10.Final \ lib \ required \ commons-collections-3.1.jar
• hibernate-distribution-3.6.10.Final \ lib \ required \ dom4j-1.6.1.jar
• hibernate-distribution-3.6.10.Final \ lib \ required \ javassist-3.12.0.GA.jar
• hibernate-distribution-3.6.10.Final \ lib \ required \ jta-1.1.jar
• hibernate-distribution-3.6.10.Final \ lib \ required \ slf4j-api-1.6.1.jar
• PostgreSQL相關9.0-802.jdbc3.jar

我注意到，休眠工具插件在其插件一些較舊的罈子BTW文件夾 （例如是版本1.5.8 SLF4J）在此期間，我會嘗試buddyloading

我第一次嘗試使用代碼生成我有這樣的事情：

org.hibernate.console.HibernateConsoleRuntimeException: Received a NoClassDefFoundError, probably the console configuration classpath is incomplete or contains conflicting versions of the same class Received a NoClassDefFoundError, probably the console configuration classpath is incomplete or contains conflicting versions of the same class java.lang.NoClassDefFoundError: org/objectweb/asm/Type org/objectweb/asm/Type  
java.lang.NoClassDefFoundError: org/objectweb/asm/Type org/objectweb/asm/Type   
java.lang.ClassNotFoundException: org.objectweb.asm.Type  org.objectweb.asm.Type  

之後，我只得到[...]cfg.reveng.OverrideRepository error。

如果有人有任何補充，請花時間做，因爲我有。

感謝

而且BTW我不能相信任何人在社會上曾經遇到過這個錯誤/問題

Answer 2

與NoClassDefFoundError的嚴重痛苦小時之後，我終於找到了解決辦法。主要重點：hibernate版本的庫應該與選定的Hibernate版本的控制檯配置（點3）相匹配。

檢查表：

1. 確保你已經下載了最新版本的Hibernate插件（即適合你的Eclipse的版本）。爲了得到它去幫助 - > Eclipse Marketplace->輸入：hibernate（eclipse版本名稱，例如luna）。選擇最新的JBoss工具，並選擇Hibernate和JBoss Maven Hibernate配置器。

2. 從http://hibernate.org/orm/downloads/下載最新的jar文件。將這些文件存儲在構建路徑中的文件夾中。

3. 在創建Hibernate控制檯配置時，請確保從下拉列表中選擇最新的Hibernate Version。例如在我的情況下，因爲我有建立路徑中的Hibernate 4.x jar文件，選擇版本4.3。解決問題。

嘗試從控制檯配置的下拉列表中更改Hibernate版本。它可以解決這個問題。

Answer 3

我在使用hibernate逆向工程時也遇到過這個問題，並且我遭受了近3天的困擾，但終於找到了解決方案。

1. 爲了在休眠工作，逆向工程，你並不需要顯式地添加任何休眠相關的jar，因爲它使用Hibernate的工具插件走來，只有一點是你必須添加的jdbc罐子相應的數據庫。

2. 創建您選擇在Eclipse的角度來看休眠選項項目之後，你會選擇File => New =>Hibernate Console Configuration

3. 在這裏，你必須做的Hibernate控制檯配置中，你有「Hibernate的版本」確保什麼以往版本中，你已經在這裏選擇你必須在創建Hibernate配置文件這不過是的hibernate.cfg.xml，如果你會做同樣的，你不會得到這個錯誤選擇相同：

org.hibernate.console.HibernateConsoleRuntimeException: Received a NoClassDefFoundError, probably the console configuration classpath is incomplete or contains conflicting versions of the same class
