Bing-ok created VFS-777:
---------------------------
Summary: "NoSuchMethodErrors" due to multiple versions of
commons-codec:commons-codec:jar
Key: VFS-777
URL: https://issues.apache.org/jira/browse/VFS-777
Project: Commons VFS
Issue Type: Bug
Affects Versions: 2.7.0
Reporter: Bing-ok
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.
As _*commons-codec:commons-codec:1.11*_ and
_*commons-codec:commons-codec:1.13*_ have not been loaded during the building
process, several methods are missing. However, the missing methods:
*_1. org.apache.commons.codec.binary.Base64: void init (int)_*
{noformat}
paths------
<org.apache.commons.vfs2.provider.http4.Http4FileObject:
org.apache.http.HttpResponse
executeHttpUriRequest(org.apache.http.client.methods.HttpUriRequest)>
commons-vfs-master\commons-vfs2\target\classes

<org.apache.commons.codec.binary.Base64: void <init>(int)>{noformat}
The above missing methods are actually referenced by *_commons-vfs(commons-vfs2
module)_*, which will cause "NoSuchMethodErrors" at runtime.
Suggested fixing solutions:
1. Upgrade dependency _*commons-codec:commons-codec*_ from _*1.2*_ to _*1.13*_.
2.Use configuration attribute <dependencyManagement> to unify the version of
library _*commons-codec:commons-codec*_ to be *_1.13_* in
commons-vfs(commons-vfs2 module)'s pom file.
3.use <exclude> to exclude _*commons-codec:commons-codec:1.2*_ from the
dependency tree.
Please let me know which solution do you prefer? I can submit a PR to fix it.
Thank you very much for your attention.
Best regards,
