使用bndtools包装从默认包导入的第三方jar [英] Wrap third party jar that imports from default package using bndtools

问题描述

我想包装第三方jar。不幸的是，供应商将一个单一类（a.class）与一个方法放在默认包中。

I want to wrap a third party jar. Unfortunately the vendor placed one single class (a.class) with one single method into the default package.

当我尝试使用 Include-Resource：@ lib / acme-8.0.jar 来包含资源时，它导致以下错误：

When I try to include the resource using Include-Resource: @lib/acme-8.0.jar, it results in the following error:

The default package '.' is not permitted by the Import-Package syntax.
This can be caused by compile errors in Eclipse because Eclipse creates valid class files regardless of compile errors.
The following package(s) import from the default package [com.acme.util]

bnd print -all acme-8.0.jar 给我以下输出（缩写，供应商名称替换为极致）

bnd print -all acme-8.0.jar gives me the following output (shortened, vendor name replaced with acme)

如果我正确理解了这个输出，几个包使用默认包。这怎么可能呢？据我所知，您无法从默认包中导入类。

If I understand this output correctly, several packages use the default package. How is that even possible? As far is I know, you can not import classes from the default package.

我已经与移动违规类的请求联系了供应商。有可能他不会遵循我的建议。

I already contacted the vendor with the request to move the offending class. Chances are, that he will not follow my suggestion.

是否有解决方法来处理默认包中的类？

Is there a workaround to handle classes in the default package?

推荐答案

您可能可以使用以下选项：

You probably can get away with the following option:

 -fixupmessages: "The default package "
