[FIXED] java.lang.NoClassDefFoundError: org/apache/commons/io/output/UnsynchronizedByteArrayOutputStream

Issue

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.

Attached my testutil and pom.xml file for reference. Attached image highlighted line im facing the issue.testutil

Solution

From the javadoc of UnsynchronizedByteArrayOutputStream: Since:2.7

So change 2.6 to 2.7 .
