向 Maven-Java-project 添加持久性时出错（org.codehaus.mojo）？

Question

当向我的 Maven-Java 项目添加持久性时，我可以成功构建和编译（Netbeans 中的“清理和构建项目”，我想它确实 mvn 站点）项目，但我不会之后无法启动它（Netbeans 中的“运行项目”）。

我已经尝试了一段时间没有成功。例如，我尝试删除 pom.xml 中的 org.codehaus.mojo 插件，尽管我的成功没有改变。

有人知道这个问题吗？我对 MySQL 数据库的设置是否有任何错误配置？还是 pom.xml 中有错误？还是在persistence.xml中？

来自 NetBeans IDE 的错误：

我最近在 NetBeans 中遇到了类似的问题，现在找到了解决方法。当我添加一个 EntityClass 并让 NetBeans 自动添加持久性单元等时，问题首先开始。

问题似乎是由持久性单元将文件添加到您的项目 META-INF 文件夹中造成的，该文件夹将使用不同的技术来计算 jar 签名或类似的东西。

要删除这些文件，请在 pom 中的 exec-maven-plugin 之后添加：

<plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>truezip-maven-plugin</artifactId>
            <version>1.2</version>
            <executions>
                <execution>
                    <id>remove-RSA-and-SF-files</id>
                    <goals>
                        <goal>remove</goal>
                    </goals>
                    <phase>package</phase>
                    <configuration>
                        <fileset>
                            <directory>${archive}/META-INF</directory>
                            <includes>
                                <include>**/*.RSA</include>
                                <include>**/*.SF</include>
                                <include>**/*.DSA</include>
                            </includes>
                        </fileset>
                    </configuration>
                </execution>
            </executions>
</plugin>

您还需要添加指向您的 .jar 文件的存档变量：

<archive>target/projName-1.0-SNAPSHOT.jar</archive>

最后在 nbactions.xml 中添加到你的运行任务：

<goal>org.codehaus.mojo:truezip-maven-plugin:1.2:remove</goal>

就在之前：

<goal>org.codehaus.mojo:exec-maven-plugin:1.2.1:exec</goal>

希望有帮助！
