java.lang.ClassNotFoundException: com.google.api.client.util.Preconditions

Hi

im trying to use oAuth2 with the webServerClient connection, and i get a "java.lang.ClassNotFoundException: com.google.api.client.util.Preconditions" when executing the following code:

[code]
GoogleAuthorizationCodeFlow authorizationFlow = new GoogleAuthorizationCodeFlow.Builder(
                new NetHttpTransport(),
                new JacksonFactory(),
                CLIENT_ID,
                CLIENT_SECRET,
                Lists.newArrayList(SCOPE))
        .setApprovalPrompt("force")
        // Set the access type to offline so that the token can be refreshed.
        .setAccessType("offline").build();
[/code]

Can anybody tell me why or what code to use instead because i do have the access to the package com.google.api.client.util. but there really is no such class called Preconditions.

Hi,

It's most likely you are missing some dependent jars.

Are you using Maven?

Either way, please read this quick start guide to setup the development environment.

I am getting the same error.  I am using Maven, something is mucked up with the poms if this class cannot be found.  Any solution so far?

I am getting the same error and using Maven, something is mucked up with the poms that needs to be fixed.  I do not know which jar this class is to be found.  This was working with an earlier version of the API jar in my pom, I just updated to the latest version and now have a problem finding this class and cannot compile.  any ideas?

I am using Maven and things will compile, this error only appears at runtime.  It looks like Preconditions is instantiated at runtime and cannot be found.

Hi, 

Can you please try running the GetRefreshToken example via the command line with the adwords-axis-example.1-17.0.tar.gz?

(Please refer these steps)

I also tested using the same bundle and it worked well. 

If it works from the command line, there should be an environmental issue with your web application setting.

Hi,

Take a look at this post:

It's possible that you are having the same problem that I had past week.

Hi, 

Wierd... It worked fine with the adwords-axis-example.1-17.0.tar.gz and the pom.xml as is. 

Can you please attach your pom.xml in that thread?
