Error with ANT

[Sander Jochems]

Hello,

When I use the ant I get an error.

D:\Programmas\Software\appinventor-sources\appinventor>ant clean

How can I fix this?

[Evan Patton]

Ant 1.10 requires Java 8 or higher. You will either need to downgrade ant to 1.9 or earlier, or upgrade your version of Java. Given that Java 7 is required for working with the App Engine development server, you may want to downgrade ant.

That's because you don't have GIT OR its not in the PATH.

Download git: https://git-scm.com/

After download and installation, ensure folder is in path.

What do I need to do to fix this?

[Gousesakhalean Mohammad]

Hi Sander,

http://ant.apache.org/bindownload.cgi

Download apache ant 1.9 from the above site,

It is working for me.

Thanks,

Gouse

You are probably using an Android Support v4 library which does not contain following package: android.support.v4.widget or you haven't imported a library.

[Evan Patton]

I think the class in question comes from the Leanback support library, which requires a min SDK of 17. We don't have support for it, but it might be possible to build a component with it (although I'm skeptical).
