在存储库中，我看到在commons-lang/commons-lang/文件夹中

其中有四个是2.1、2.4、2.5、2.6，但是2.1和2.4在文件夹中没有jar，只有其他文件。2.5和2.6文件夹中有jars。

在org/apache/commons/commons-lang3文件夹中，我看到一个带有jar的3.1

我已经把它分解到了绝对的基本观察点，这样有类似经验的人就能帮我解决问题。

查看您的commons版本，我的版本为2.6，使用的是sudo find /颇具grep commons

添加插件之前的依赖项，并确保id以i(而不是i)开头：

代码语言：javascript
复制
<dependency> 
    <groupId>commons-lang</groupId> 
    <artifactId>commons-lang</artifactId> 
    <version>2.6</version>
</dependency>

不像每个wiki那样构建，没有controller/opendaylight/distribution/opendaylight/target来./run.sh，所以我现在正在寻找吗?？

由于OP没有指定细节，我猜这可能是关于在Ubuntu 14上运行maven。

Maven在Ubuntu上的打包似乎有一些“问题”。在Ubuntu14.04.1LTS中使用apt-get install maven并试图用mvn package打包我的项目之后，我得到了同样的异常。

来自github的评论的解决办法是：

代码语言：javascript
复制
sudo ln -s ../../java/commons-lang.jar /usr/share/maven/lib

至少在我的情况下。

您不能将commons-lang声明为依赖项。添加

代码语言：javascript
复制
<dependencies>
<dependency>
    <groupId>commons-lang</groupId>
    <artifactId>commons-lang</artifactId>
    <version>2.3</version>
</dependency>
</dependencies>

给你的pom.xml

您的pom.xml应该如下所示：

代码语言：javascript
复制
<dependencies>
<dependency>
    <groupId>commons-lang</groupId>
    <artifactId>commons-lang</artifactId>
    <version>2.3</version>
