在我的 portlet 中添加 postgres jdbc 后，我的 portlet 没有启动
My portlet don't start after the adding of postgres jdbc in my portlet
我的 OSGI portlet 有问题。我通过 bnd.bnd 在我的 portlet 中添加了 jdbc.jar。
我是这样做的：
Bundle-Name: bd-portlet
Bundle-SymbolicName: com.test
Bundle-Version: 1.0.0
Export-Package: com.test.constants
Bundle-ClassPath:\
.,\
lib/postgresql.jar
-includeresource:\
lib/postgresql.jar=postgresql-42.2.5.jar
我看到我的 portlet 的 jar 并且 jdbc 存在于 lib 文件夹中。但是现在我的 portlet 没有启动。这是屏幕输出：

我将 com.sun.jna 添加到我的 build.gradle 和我的 bnd.bnd 文件中：
Bundle-Name: bd-portlet
Bundle-SymbolicName: com.test
Bundle-Version: 1.0.0
Export-Package: com.test.constants
Bundle-ClassPath:\
.,\
lib/postgresql.jar,\lib/jna.jar
-includeresource:\
lib/postgresql.jar=postgresql-42.2.5.jar,\
lib/jna.jar=jna-3.0.9.jar
，但没有任何改变。我的 portlet 没有启动。有人有想法吗？
我解决了这个问题。当我们有：
org.osgi.framework.BundleException: Could not resolve module: com.test [1012]_ Unresolved requirement: Import-Package: xxxxxx [Sanitized]
只需添加：
Import-Package: \
!xxxxxx,\
*
在您的 bnd.bnd 文件中。就我而言，我将添加：
Import-Package: \
!com.sun.*,\
*
在我的 bnd.bnd 文件中。
