[FIXED] The value of attribute "value" associated with an element type "property" must not contain the '<' character

Issue

<bean id="fileDiffTaskelt" class="org.springframework.batch.core.step.tasklet.SystemCommandTasklet" scope="step">
<property name="command" value="diff #{jobParameters['INPUT_FILE']} #{jobParameters['PREVIOUS_FILE']} |  grep -e '<' -e '>' | grep -x '.\{20\}' > #{jobParameters['FILTERED_FILE']}"/>
<property name="timeout" value="60000"/>
<property name="workingDirectory" value="/tmp/hub"/>
</bean>

I'm getting this error in my IDE : The value of attribute "value" associated with an element type "property" must not contain the '<' character. Im using this character in my grep command and is very essential, stuck here.

Solution

You can use Escape Strings for the same.

Replace '<' in value attribute as '<' .

    <property name="command" value="diff #{jobParameters['INPUT_FILE']}
      #{jobParameters['PREVIOUS_FILE']} |  grep -e &apos;&lt;&apos; -e &apos;&gt;&apos; 
      | grep -x '.\{20\}' > #{jobParameters['FILTERED_FILE']}"/>

Similarly use for appropriate escape strings for '>'

XML Escape Strings
