Question

我在使用maven构建OSGi项目时遇到了问题。我开始得到一个奇怪的错误。

我认为某些资源已损坏。但我不知道哪一个。我试图删除.m2 / repository。但问题仍然存在。有关如何纠正这个问题的任何想法？

根据要求，maven-bundle-plugin配置：

<plugin>
            <groupId>org.apache.felix</groupId>
            <artifactId>maven-bundle-plugin</artifactId>
            <extensions>true</extensions>
            <configuration>
                <instructions>
                    <Import-Package>*</Import-Package>
                    <Export-Package>org.opennaas.extensions.idb.*;version="${project.version}"</Export-Package>
                    <Meta-Persistence>META-INF/persistence.xml</Meta-Persistence>
                </instructions>
            </configuration>
        </plugin>

Answer 1

问题实际上是一个编码问题。可能与persistence.xml文件。我重新保存了资源目录下的所有文本文件，它又开始工作了

Answer 2

遇到同样的错误我想分享我的发现，这可能会有所帮助，直到诊断信息得到改善。

我添加

时收到错误

<resources>
  <resource>
    <directory>src/main/resources</directory>
    <filtering>true</filtering>
  </resource>
</resources>

到我的bundle pom.xml。我的资源目录中的一个文件存在编码问题，并使用

<includes>

指令与另一个文件后我能够找出它是哪一个。

maven-bundle-plugin中的内部错误。嵌入式错误：打开资源
