-------------------------------------------------------------

I am on a mac with 
{code:none}
java -version
java version "1.7.0_75"
Java(TM) SE Runtime Environment (build 1.7.0_75-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.75-b04, mixed mode)
{code}

When I download the jar from Apache I can untar fine.
When I pull via gradle from mvnrepository I have the issue. I am bringing in 
the following dependencies
{code:none}
'org.apache.flink:flink-clients:0.10.2-hadoop1'
'org.apache.flink:flink-scala:0.10.2-hadoop1'
{code}

The file in the gradle cache is the one with the issue (I have deleted the 
cached files and allowed gradle to pull again) .

This sounds more like a gradle-ism than a jar'ing problem. I think we can mark 
this as resolved. I'll re-open if I continue to have issues.

I don't know much mvn packaging I am afraid, so I don't know if the folllowing 
is relevent, but...
{code:none}
cd /path/to/gradle/cache
md5 flink-runtime-0.10.2-hadoop1.jar
MD5 (flink-runtime-0.10.2-hadoop1.jar) = dc747ec3da5ddc8556aa707b3c5fc9a2

cd /path/to/mvn/direct/download
MD5 (/Users/paul/dev/tmp/flink-core-0.10.2-hadoop1.jar) = 
54a4c422a57baecb48d609e7187448d8
{code}

>             Project: Flink
>          Issue Type: Bug
>          Components: Distributed Runtime
>    Affects Versions: 0.10.2
>            Reporter: Paul Harris
>
> Unjaring flink-runtime-0.10.2-hadoop-1 results in an error.
> Steps to reproduce
> {code:none}
> jar xf flink-runtime-0.10.2-hadoop1.jar
> {code}
> Result...
> {code:none}
> java.io.IOException: META-INF/license : could not create directory
>       at sun.tools.jar.Main.extractFile(Main.java:934)
>       at sun.tools.jar.Main.extract(Main.java:877)
>       at sun.tools.jar.Main.run(Main.java:263)
>       at sun.tools.jar.Main.main(Main.java:1177)
> {code}
> This is the result of the jar containing a file 'license' and a directory 
> license'. The file is unpacked first, preventing the directory being unpacked 
> to the same name.
