Wget not working to load jar file from maven repo

I am trying to download a single jar file from the maven repository from the url below.

http://repo1.maven.org/maven2/com/google/guava/guava-testlib/10.0/guava-testlib-10.0.jar

  • Downloading in the browser works fine, and I get the file as expected.

  • 'wget' is loading something, but the file I get is not valid. Running "jar -tf" in the downloaded file gives "ZipException: error opening zip file."

  • Downloading the file programmatically from Java (“InputStream” from the URL written to “FileOutputStream”) downloads something and creates the file. Opening it with WinZip / 7-Zip, it contains one file called "guava-testlib-10.0", which looks like the jar archive that I expected to receive.

  • wget another jar works as expected, at least sometimes (with user agent string -U )

Is this some tricky interaction between wget / maven or Java / maven? Is this the wrong jar file that my browser correctly understands and downloads? Both of them seem implausible to me.

wget is usually blocked from the central maven repository because some people do not play well and try to work too much. Try installing the user agent:

 wget -U "Any User Agent" http://repo1.maven.org/maven2/com/google/guava/guava-testlib/10.0/guava-testlib-10.0.jar
