How can fix this issue.

[sathiyaselvam]

Add dependency jar with correct format,
dependency
groupId-com.itextpdf
artifactId - itextpdf
version-5.5.4
optional-true

// Bouncycastle dependencies necessary as they are optional = true
// in itextpdf ... but they're not-so-optional in reality
dependency
groupId-org.bouncycastle
artifactId-bcprov-jdk15on
version-1.49

dependency
groupId-org.bouncycastle
artifactId-bcpkix-jdk15on
version-1.49
