Bumping version not working

[jrajput]

Hi,
I am using grunt-maven-tasks version 1.3.2 and getting following error when doing maven:release. Although maven deploy works fine since it doesn't do bumping the version. My package.json has version : "version": "1.2.0-SNAPSHOT".
Also is there any option to stop bumping of version and commit on git automatically?

Bumping version to 1.2.0...ERROR

Failed to bump version to 1.2.0

My grunt settings are :
maven: {
options: {
groupId: mavenGroupId,
artifactId: mavenArtifactId,
commitPrefix: ' ',
repositoryId: ''
},
deploy: {
options: { url: mavenSanpshotUrl },
src: [ disuiPath + '//*' ]
},
release: {
options: { url: mavenReleaseUrl, mode:'patch'},
src: [ disuiPath + '//*' ]
}
}
