PowerShell: Get version number from maven-metadata.xml

Simple task. There is maven-metadata.xml file stored on internet and you need to get version number of latest jar.

Let’s use maven-metadata.xml from Forsqaure Java API.

File looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<metadata modelVersion="1.1.0">
  <groupId>fi.foyt</groupId>
  <artifactId>foursquare-api</artifactId>
  <version>1.0.2-SNAPSHOT</version>
  <versioning>
    <snapshot>
      <timestamp>20120607.214317</timestamp>
      <buildNumber>6</buildNumber>
    </snapshot>
    <lastUpdated>20120607214317</lastUpdated>
    <snapshotVersions>
      <snapshotVersion>
        <extension>jar</extension>
        <value>1.0.2-20120607.214317-6</value>
        <updated>20120607214317</updated>
      </snapshotVersion>
    </snapshotVersions>
  </versioning>
</metadata>

Powershell script is very simple:

$url = "https://foursquare-api-java.googlecode.com/svn-history/r288/repository/fi/foyt/foursquare-api/1.0.2-SNAPSHOT/maven-metadata.xml"
$data =(New-Object System.Net.WebClient).DownloadString($url)
$data.metadata.versioning.snapshotVersions.snapshotVersion[0].value

Result:

1.0.2-20120607.214317-6
