This thread discusses the Content article: Subversion Access

A problem encountered by Windows users attempting to access the ECharts SVN source code repository via SVN clients has been fixed by sourceforge admins. The problem is described here.

The solution to the problem implemented by sourceforge requires that SVN clients access the repository using a new URL. For example, the old way to access the ECharts trunk was to use https://svn.sourceforge.net/svnroot/echarts/trunk/EChartsCPL. The new way to access the ECharts trunk is to use https://echarts.svn.sourceforge.net/svnroot/echarts/trunk/EChartsCPL.

In summary, if you've never checked out the code before then use the new URL as described here regardless of your OS since this is the new officially sanctioned way to access SVN on sourceforge.

If you've already checked out code into your own local repository then you have three options:

• Delete your repository and check out a new version using the new URL.
• Relocate your repository's URL using the procedure described here.
• Don't do anything if it's working for you using the old URL. This is not recommended. Even though sourceforge appears to be maintaining access via the old URL, it's not clear how long this will last.
