[0pdd]

The puzzle 1602-59e4ff34 from #1602 has to be resolved:

eo/eo-maven-plugin/src/main/java/org/eolang/maven/DiscoverMojo.java

Lines 128 to 134 in 9a7619f

	* @todo #1602:30min Simplify xpath. Current implementation for building
	* xpath with and without versions is quite ugly. For some reason
	* if we try to take `/concat(@base,'|',@ver)` and there are object without
	* attribute `ver` - xpath returns nothing. So we need to take `/@base`
	* from objects where attribute `ver` is not present in both cases and
	* then if flag `withVersions` is `true` - take `concat(@base,'|',@ver)`
	* from objects attribute `ver` is present.

The puzzle was created by rultor on 14-Jul-23.

Estimate: 30 minutes, role: DEV.
