Please Solve this error
Which command you had ran?
1 Like
I ran ant . I have downloaded the appinventor sources again. Now, going to run it again
Any other?
Make sure you are in proper directly and before ant command run this one
$ git remote add upstream https://github.com/mit-cml/appinventor-sources.git
I have run it again and it says that something like "remote git already"
$ git submodule update --init
Run this one
Then make sure you are in appinventor-source/appinventor directory and run this..
$ ant MakeAuthKey
I setup my sources again and it starts working but the components which is added newly. it shows me a error.

faultData = java.lang.UnsupportedOperationException: unknown component: AnimationUtilities
projectId = -1
What does this mean ??
Is there anything I am missing (There is no error while running ant extensions and ant)
ant extensions is not command for adding new components
Most probably this error occurs when you specify that a component is visible, but don't add a mock for this component, and therefore, an exception is thrown here. If you mean to make this component visible, you should create a new mock file inside simple/components directory, and edit the SimpleComponentDescriptor to create the mock in case the component type is equal to "AnimationUtilities". If you didn't meant to make the component is visible, you just need the need specify that the component is nonVisible from the designerComponent annotation:
@DesignerComponent(version = YaVersion.COMPONENT_VERSION,
description = "",
category = ComponentCategory.SOMECATEGORY,
nonVisible = true,
iconName = "")
And make your component class a subclass if the AndroidNonvisibleComponent class:
public class Component extends AndroidNonvisibleComponent {
