Answer 1

You receive this error because the value of the url is provided by a maven property, referred as ${liquibase.mysql.url}
You can set the value for maven properties in your pom like:
<project>
[...]
<properties>
<liquibase.mysql.url>jdbc:mysql://127.0.0.1:3306</liquibase.mysql.url>
<liquibase.mysql.username>someuser</liquibase.mysql.username>
[...]
</properties>
[...]
The liquibase plugin also provides possibility to read the configuration properties from a property file e.g. src/main/resources/liquibase.properties
If you choose this, you need to configure the liquibase maven plugin by replacing the conofiguration section in the pom like:
[...]
<configuration>
<propertyFile>src/main/resources/liquibase.properties</propertyFile>
</configuration>
[...]
Then the liquibase properties should look like
url=jdbc:mysql://127.0.0.1:3306
username=someuser
dropFirst=true
changeLogFile=yourfile
[...]
More information is here: http://www.liquibase.org/documentation/maven/index.html#using_configuration_property_files

Answer 2

You need to set your variables ${liquabase.mysql.url} and so forth in your .m2/settings.xml. More details here: Missing maven .m2 folder
You also need to run mvn liquibase:update

Answer 3

First of all you are using a phase process-resource, which is basically used when you want to work on your changeLog from the output target directories, and if you are trying to use the filtering in your resource files using maven resource filtering plugin.
And I don't know for what purpose you are actually using the prepare-package or any such phase multiple times, maven with liquibase is not setup like this, you should have one master changelog, which should include your other upgrades, with some preCondition checks in each of your upgrades.
Your directory structure should be something like following, if you want to use your process-resource phase, and intended to do some kind of filtering in resource files.
src/
`-- main
|-- java
`-- resources
|-- changelog-1.0.0.xml
|-- changelog-1.1.0.xml
|-- changelog-install.xml
