Amazing! Thank you very much. Can you give some information on the template building rules?
For example, I'd like to add the object package name.

@dmarrazzo Here are the supported template variables.

${object.className}	inserts the class name as a simple String
${object.getClassName}	inserts a call to this.getClass.getName()
${object.superToString}	inserts a call to super.toString()
${object.hashCode}	inserts a call to this.hashCode()
${object.identityHashCode}	inserts a call to System.identityHashCode(this)
${member.name}	inserts the first member's name
${member.name()}	inserts the first member's name followed by parenthesis in case of methods
${member.value}	inserts the first member's value
${otherMembers}	inserts the remaining members. For each member, the template fragment between the first and the last ${member.} variable is evaluated and appended to the result. The characters between the last ${member.} and ${otherMembers} define the separator that is inserted between members (${otherMembers} must stand after the last ${member.*} variable).
