@gaurabhi1986 Please check pom.xml and ensure all dependencies are installed properly. Check out the following snippet from pom.xml in this repo:

    <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.11</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-io</artifactId>
            <version>1.3.2</version>
        </dependency>
        <dependency>
            <groupId>org.json</groupId>
            <artifactId>json</artifactId>
            <version>20160212</version>
        </dependency>
    </dependencies>

I believe the error is coming since you haven't installed commons-io. Please check.

Please follow these steps and let us know if it worked:

  1. Clone this fork.
  2. Switch to example branch.
  3. Run mvn compile && mvn exec:java -Dexec.mainClass=example.BrowserStackLocalExample

This will run the example code which shows how to use com.browserstack.local.Local

Hi @tr4n2uil

I am using this example as a reference to start Browserstack local, but still facing same problem, have modified pom.xml but nothing is working same error coming each time.

Thanks,

Can you try mvn clean and then mvn compile && mvn exec:java -Dexec.mainClass=example.BrowserStackLocalExample as earlier ?

Also post the output (with error, if any) please.

Seems like didn't set your access key in environment.

Run the following, if linux/mac

export BROWSERSTACK_ACCESS_KEY=<your access key here>

or if windows then

set BROWSERSTACK_ACCESS_KEY=<your access key here>

then run as before

mvn clean && mvn compile && mvn -e exec:java -Dexec.mainClass=example.BrowserStackLocalExample

Again, post the output (with error, if any) please.

Cool. Pushed a minor change. Can you pull and re-run ?

git pull origin example

mvn clean && mvn compile && mvn -e exec:java -Dexec.mainClass=example.BrowserStackLocalExample

Hi @tr4n2uil ..

Please resolve this issues...

Hey @gaurabhi1986

I just tested the example branch on the clone on Ubuntu 16.04 vagrant image. Things are working fine for me.
Also, note that the BROWSERSTACK_USER env variable was used instead of BROWSERSTACK_USERNAME, only in the example. We pushed a commit for that, but anyways that error doesn't seem relevant to your case.

In your case, the issue seems to be with the BrowserStackLocal binary connection.
Relevant change - environment variable BROWSERSTACK_ACCESS_KEY. Make sure that you did export and not just set the variable (It works smoothly in my case).

And to resolve this faster, without delays, just drop an email to [email protected] with the subject Getting "NoClassDefFoundError" Exception when executing Test on Ubuntu 16.04 and make sure you mention if you are behind a proxy/firewall. Hoping to resolve this quickly.

Hi @tr4n2uil

I am not exporting env variable I am simply assigning string value to username and key variables.

Same code sample is working when I set bsLocalArgs.put("binarypath", "/browserstack/BrowserStackLocal");

but it does not work when i did not set localbinary path.

Can you please let me know do I need to set any proxy or something.
