在我的Maven-Java项目中添加持久性时，我可以成功构建和编译（Netbeans中的“清理和构建项目”，我认为它确实 mvn site ）项目，但我赢了之后可以启动它（Netbeans中的“运行项目”）。
我一直在尝试一段时间没有成功。例如，我试图删除pom.xml中的org.codehaus.mojo插件，尽管我的成功没有变化。
有谁知道这个问题？我的MySQL数据库设置是否有任何错误的配置？或者pom.xml中是否有错误？或者在persistence.xml中？
NetBeans IDE出错：

Running NetBeans Compile On Save execution. Phase execution is skipped and output directories of dependency projects (with Compile on Save turned on) will be used instead of their jar artifacts.

答案 0 :(得分：0)
我最近在NetBeans中遇到了类似的问题，现在找到了修复程序。当我添加EntityClass并让NetBeans自动添加持久性单元等时，问题才开始。
问题似乎是由持久性单元向项目META-INF文件夹添加文件引起的，该文件夹将使用不同的技术来计算jars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>
您还需要添加归档变量，该变量指向.jar文件：
<archive>target/projName-1.0-SNAPSHOT.jar</archive>
最后添加到nbactions.xml中的运行任务：
<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>
希望有所帮助！
