例如使用maven编译使用了mina的包的工程,出现如下提示:

这个问题可能是依赖的项目打包成bundle造成,比如mina就是这样的,打包成bundle,例子:
- <dependency>
- <groupId>org.apache.mina</groupId>
- <artifactId>mina-core</artifactId>
- <version>2.0.4</version>
- <type>bundle</type>
- <scope>compile</scope>
- </dependency>
加入上面依赖出现错误如下:

11-9-26
上午10时21分30秒: Build errors for test-http-mina;

原因
mina打包为了bundle格式,为此,需要添加插件
在maven的pom.xml中plugins段中加入plugin即可
- <plugin>
- <groupId>org.apache.felix</groupId>
- <artifactId>maven-bundle-plugin</artifactId>
- <extensions>true</extensions>
- </plugin>
- <extensions>true</extensions>
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<version>2.3.7</version>
<extensions>true</extensions>
</plugin>
<groupId>org.apache.felix</groupId>
