When I try to execute automation script I'm getting error as "java.lang.NoClassDefFoundError: org/apache/commons/io/output/UnsynchronizedByteArrayOutputStream"

I've added

<dependency>
            <groupId>commons-io</groupId>
            <artifactId>commons-io</artifactId>
            <version>2.6</version>
        </dependency>

in the pom.xml file. But still I'm facing the error.

CodePudding user response：

From the javadoc of UnsynchronizedByteArrayOutputStream: Since:2.7

So change 2.6 to 2.7 .
