MVN：Maven bundle error：解決Maven管理的項目下"Missing artifact xxx bundle"問題

想仔細看看mina架構，有強迫症的我不願意直接引用下載的包，折騰了一個晚上maven和eclipse集成，用了最新版本。感謝蝸牛的文章。

MVN：Maven bundle error：解決Maven管理的項目下"Missing artifact xxx bundle"問題

例如使用maven編譯使用了mina的包的工程，出現如下提示:

這個問題可能是依賴的項目打包成bundle造成，比如mina就是這樣的，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>

加入上面依賴出現錯誤如下：

11-9-26 上午10時21分30秒: Maven Builder: AUTO_BUILD requireFullBuild

11-9-26 上午10時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時22分11秒: Maven Builder: AUTO_BUILD 

原因

mina打包爲了bundle格式，爲此，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>

其中

<extensions>true</extensions>

是必須的。
