Parse Java version targeted by Maven - maven-compiler-plugin

[abdennour]

Under build>plugins >plugin(artifactId=maven-compiler-plugin) > configuration> target

example 1 working with Java 15

	<build>
			<plugin>
				<artifactId>maven-compiler-plugin</artifactId>
				<inherited>true</inherited>
				<configuration>
					<source>15</source>
					<target>15</target>
				</configuration>
			</plugin>
    ....
  </build>

example 2 Working with Java 8 but the info is in section.

 	<properties>
		<java.version>1.8</java.version>
        </properties>
          .......
	<build>
			<plugin>
				<artifactId>maven-compiler-plugin</artifactId>
				<inherited>true</inherited>
				<configuration>
					<source>${java.version}</source>
					<target>${java.version}</target>
				</configuration>
			</plugin>
    ....
  </build>

Do you have plan to support that parsing ?

Hello,

Currently, this library supports parsing plugins, but the configuration is not mapped yet:

mvnparser/parser.go

Line 102 in 23a6b7f

//todo something like: Configuration map[string]string `xml:"configuration"`

So this would be the first thing to do.

Then adding a FindPlugin(string): (Plugin, bool) methods on the Project struct, will allow us to do something like the following:

project := &MavenProject{}
plugin, exists := project.FindPlugin("maven-compiler-plugin")

if exists {
     fmt.Println(plugin.Configuration["target"])
}

I can take a look to make this PR. However, I do not plan to supports <properties> parsing and extrapolation in the near future because of the amount of work needed (and because I don't need the feature). If you want it, please feel free to raise a PR :)
