> h1. Issue description
> Hi, there are multiple versions of _*commons-codec:commons-codec*_ in *_commons-vfs(commons-vfs2 module)_*. As shown in the following dependency tree, according to Maven's "nearest wins" strategy, only _*commons-codec:commons-codec:1.2*_ can be loaded, _*commons-codec:commons-codec:1.11*_ and _*commons-codec:commons-codec:1.13*_ will be shadowed.
> However, one method defined in shadowed version _*commons-codec:commons-codec:1.11*_ is referenced by client project via _*org.apache.httpcomponents:httpclient:4.5.12*_, but missing in the actually loaded version _*commons-codec:commons-codec:1.2*_.
> For instance, the following missing method(defined in _*commons-codec:commons-codec:1.11*_) is actually referenced by *_commons-vfs(commons-vfs2 module)_*, which will introduce a runtime error(i.e., "NoSuchMethodError") into *_commons-vfs(commons-vfs2 module)_*.
> *_Missing method: org.apache.commons.codec.binary.Base64: void init (int)_* is invoked by *_commons-vfs(commons-vfs2 module)_* via the following path:

> h1. Suggested fixing solutions
> 1.Use configuration attribute <dependencyManagement> to unify the version of library _*commons-codec:commons-codec*_ to be *_1.11_* in commons-vfs(commons-vfs2 module)'s pom file.
> 2. Declare a direct dependency _*commons-codec:commons-codec1.11*_ to upgrade version from _*1.2*_ to _*1.11*_.
> 3.use <exclude> to exclude _*commons-codec:commons-codec:1.2*_ from the dependency tree, so that version _*1.11*_ will be loaded.
> Please let me know which solution do you prefer? I can submit a PR to fix it.
> Thank you very much for your attention.
