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>
<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: Maven Builder: AUTO_BUILD requireFullBuild
11-9-26 上午10时21分30秒: Build errors for test-http-mina; org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal on project test-http-mina: Could not resolve dependencies for project com.tecno:test-http-mina:jar:0.0.1-SNAPSHOT: Failure to find org.apache.mina:mina-core:bundle:2.0.4 in http://uk.maven.org/maven2/ was cached in the local repository, resolution will not be reattempted until the update interval of uk.maven.org has elapsed or updates are forced
11-9-26 上午10时22分11秒: Refreshing [/test-http-mina/pom.xml]
11-9-26 上午10时22分11秒: Missing artifact org.apache.mina:mina-core:bundle:2.0.4:compile
11-9-26 上午10时22分11秒: Maven Builder: AUTO_BUILD
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>
<plugin> <groupId>org.apache.felix</groupId> <artifactId>maven-bundle-plugin</artifactId> <extensions>true</extensions> </plugin>
- <extensions>true</extensions>
<extensions>true</extensions>是必须的。

今天发现,用这个方法的log4j有问题,不妨可以试试
- <dependency>
- <groupId>log4j</groupId>
- <artifactId>log4j</artifactId>
- <version>1.2.16</version>
- <type>jar</type>
- <scope>compile</scope>
- <exclusions>
- <exclusion>
- <groupId>com.sun.jmx</groupId>
- <artifactId>jmxri</artifactId>
- </exclusion>
- <exclusion>
- <groupId>com.sun.jdmk</groupId>
- <artifactId>jmxtools</artifactId>
- </exclusion>
- <exclusion>
- <groupId>javax.jms</groupId>
- <artifactId>jms</artifactId>
- </exclusion>
- </exclusions>
- </dependency>
