Question

每当我启用（maven）过滤persistence.xml文件时，我都会收到以下错误：

SEVERE: DataNucleus Enhancer completed with an error. Please review the enhancer log for full details. Some classes may have been enhanced but some caused errors
No "persistence.xml" files were found in the CLASSPATH yet you specified as input the name ("toto") of a "persistence-unit" to enhance. You must have a valid "persistence.xml" file in the CLASSPATH in a valid location to use this option.
org.datanucleus.enhancer.NucleusEnhanceException: No "persistence.xml" files were found in the CLASSPATH yet you specified as input the name ("toto") of a "persistence-unit" to enhance. You must have a valid "persistence.xml" file in the CLASSPATH in a valid location to use this option.

    at org.datanucleus.enhancer.DataNucleusEnhancer.main(DataNucleusEnhancer.java:1258)

在我的pom.xml中，我只是使用它：

<resources>
    <resource>
         <filtering>true</filtering>
         <directory>src/main/resources/META-INF/</directory>
    </resource>
</resources>

Answer 1

META-INF /应该从配置的目录元素中删除，否则Maven在过滤persistence.xml文件后不会将META-INF目录带到classes文件夹。

DataNucleus persistence.xml过滤：否＆＃34; persistence.xml＆＃34;文件在CLASSPATH中找到
