Maven published pom has invalid dependency version syntax

[RenYuENG]

The Maven artefact published to the local repo, when using gradle clean build publishToMavenLocal, has invalid dependency version syntax (using latest maven: 3.6.0):

<dependency>
  <groupId>com.google.guava</groupId>
  <artifactId>guava</artifactId>
  <version>+</version>
  <scope>compile</scope>
</dependency>
<dependency>
  <groupId>org.apache.commons</groupId>
  <artifactId>commons-lang3</artifactId>
  <version>+</version>
  <scope>compile</scope>
</dependency>
<dependency>
  <groupId>commons-io</groupId>
  <artifactId>commons-io</artifactId>
  <version>2.+</version>
  <scope>compile</scope>
</dependency>

This causes Maven to report:
[ERROR] Failed to execute goal on project NDHA-ExternalDCTool: Could not resolve dependencies for project nz.govt.natlib.ndha.externaldctool:NDHA-ExternalDCTool:jar:0.1: The following artifacts could not be resolved: com.google.guava:guava:jar:+, org.apache.commons:commons-lang3:jar:+: Could not find artifact com.google.guava:guava:jar:+ in dia-nexus (https://nexus.dia.govt.nz/repository/maven-public/) -> [Help 1]

Substituting in a fixed version number, e.g. 27.0-jre for guava resolves this issue.

The Maven Versions plugin should be used to keep the dependency version number up to date

@RenYuENG It appears that maven doesn't support the + syntax. Can you create a branch and update the versions to the last matching version. Look on maven central. Assign it to me.

@kurtlenfesty I'll make a branch and make any changes that I thought were needed to get the tool working with my Watermarker project ... might need to add some new methods to get the SIP fields I need. I'll make a merge request when you get back. Enjoy your holiday!

I'm quite able to check pull requests on my trip. No need to wait.
