fix(java): trim spaces from pom.xml fields

[DmitriyLewen]

Description

mvn ignores extra spaces in fields (artifactId, GroupId, etc.) of pom.xml files.
We need to use same logic.

example:

...
    <dependencies>
        <dependency>
            <groupId> com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind </artifactId>
            <version>2.18.0</version>
            <exclusions>
                <exclusion>
                    <groupId> com.fasterxml.jackson.core</groupId>
                    <artifactId>jackson-annotations </artifactId>
                </exclusion>
            </exclusions>
        </dependency>
    </dependencies>
</project>
