我正在构建.kar文件，但是当我运行mvn package时，我收到此错误：

我无法弄清楚造成这些错误的原因。当我阅读拆分包时，我得到了一个非常有用的建议，即应该避免拆分包。是的......我无法控制jaxb-impl，jaxb-core或com / sun /*。

有关如何解决此问题的任何想法？

2 个答案:

答案 0 :(得分：3)

Export-Package的默认值为{local-packages}而不是*

使用指令Export-Package: *，您要求bnd导出项目的所有依赖项。

删除*或使用{local-packages}

修改：

请注意，您只应从Bundle导出公共API。其他一切都应该保密。默认情况下，maven-bundle-plugin导出所有包，但包含impl或internal的包除外。如果可以，您应该坚持使用此约定并省略Export-Package指令，或明确导出您的公共包。

请检查http://mail-archives.apache.org/mod_mbox/felix-users/200709.mbox/%3CF034315F398DE24C9A76FB51DAFAB709FC9638@nets13ga.ww300.siemens.net%3E

示例为我工作：

<Export-Package>
  org.hibernate.*;version=${pkgVersion};-split-package:=merge-last                       

</Export-Package>
