I have a dependency to log4j.
dependencies {
compile group: 'log4j', name: 'log4j', version: '1.2.+'
}
The log4j has an optional dependency to javax.mail.
ivy-1.2.16.xml
<dependency org="javax.mail" name="mail" rev="1.4.1" force="true"
conf="optional->compile
,master"/>
I defined a runtime dependency, because we need the mail.
dependencies {
compile group: 'log4j', name: 'log4j', version: '1.2.+'
runtime group: 'javax.mail', name: 'mail', version: '1.+'
}
I do not want to define the version ('1.+'). But without the version I
get an error.
