Some problems were encountered while building the effective model for com.livehereandnow.mark1.sudoku:sudoku1:jar:1.0
'build.plugins.plugin.version' for org.apache.maven.plugins:maven-javadoc-plugin is missing.
'build.plugins.plugin.version' for org.apache.maven.plugins:maven-deploy-plugin is missing.
'build.plugins.plugin.version' for org.apache.maven.plugins:maven-source-plugin is missing.

It is highly recommended to fix these problems because they threaten the stability of your build.

For this reason, future Maven versions might no longer support building such malformed projects.
