How to resolve dependency errors in Maven with Nexus repository

I am a newbie with Maven/Nexus so hopefully these are simple questions i hope:

When i run mvn install on my project i get the following errors:

[WARNING] Some problems were encountered while building the effective model for com.myproj.TestProj:jar:0.0.1
[WARNING] 'build.plugins.plugin.version' for org.apache.maven.plugins:maven-compiler-plugin is missing. @ line 294, column 12
[WARNING] 'build.plugins.plugin.version' for org.apache.maven.plugins:maven-surefire-plugin is missing. @ line 304, column 12
[WARNING] 
[WARNING] It is highly recommended to fix these problems because they threaten the stability of your build.
[WARNING] 
[WARNING] For this reason, future Maven versions might no longer support building such malformed projects.

And the second error

[WARNING] The POM for oracle:ojdbc:jar:10.0.2.0 is missing, no dependency information available

For the first error i think wants me to add the version information to the following plugin

<plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <verbose>true</verbose>
                    <source>1.6</source>
                    <target>1.6</target>
                    <encoding>ISO-8859-1</encoding>
                </configuration>
            </plugin>

The question is how do i know which version to specify and where do i find out which versions are available?

The second error about the missing oracle:ojdbc:jar:10.0.2.0 artifact is one i am not quite sure what to do about. I have googled around and it seems that maybe i might have to download the driver manually and install it onto my repository locally. Is this correct?

I am using Nexus with Maven. How would i need to install the ojdbc driver onto the nexus repository?

I found this page from google - http://www.zparacha.com/include-externaljar-file-in-maven/ and it talks about about how to add the jar file to Maven. What i don't understand is what happens when i run the command described on that site to install the jar file? Will the jar file be installed on my local repository or the nexus repository?

Thanks

First off: The messages are warnings, not errors. Your project builds and runs fine without serious problems.

The plugins and their versions can be found here: http://maven.apache.org/plugins/index.html

The Oracle JDBC driver can be added as can be seen here: https://repository.sonatype.org/index.html#nexus-search;quick~ojdbc

If the error still persists after using that artifact there is not much you can do about it - except for creating your own repository, but for those warnings it is not worth the effort.
