jpa - 重新创建实体类

Question

我尝试在 netbeans 8.0.1 上运行带有 hibernate、spring 和 jpa 的 Web 应用程序，但现在我在编译应用程序时遇到了这个异常……这是以下错误:

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-    compile) on project SMSXxxxx: Compilation failure: Compilation failure:
error: Problem with Filer: Attempt to recreate a file for type  com.equitel.smsmanager.entities.TextMessageContent_
error: Problem with Filer: Attempt to recreate a file for type com.smsmanager.entities.SmsUser_

这是持久化单元，我的项目中只有一个

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence"            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

<properties>
  <property name="javax.persistence.schema-generation.database.action" value="drop-and-create"/>
</properties>
</persistence-unit>
</persistence>

我还没有解决这个错误，你能帮我解决这个问题吗？

Answer 1

由于某些原因，pom.xml 中存在依赖关系。就我而言，这导致了问题。查找并删除它:

    <dependency>
        <groupId>unknown.binary</groupId>
        <artifactId>hibernate-jpamodelgen-4.3.1.Final</artifactId>
        <version>SNAPSHOT</version>
        <scope>provided</scope>
    </dependency>

这可能是 Netbeans 中的一个错误。
