Question: With rails, I'm trying to render this JSON:

```
             options:
               { seriesType: "bars",
                 series: {1: {type: "line"}},
                 width: 375, 
                 height: 240,
                 legend: 'none',
                 pointSize: 5,
                 backgroundColor: 'transparent',
                 vAxis: { minValue: 0, maxValue: 100 }
                }

```

I'm having problems with this line

```
                 series: {1: {type: "line"}},

```

and it seems that the reason is that the key is a number {1: ...

What's the way to render a Json with a number as a key?

Answer: 
You can use the `-o` (`--offline`) option to force Maven to use your local files, e.g.

```
mvn -o clean install 

```

See [Maven Command Line Options](http://books.sonatype.com/mvnref-book/reference/running-sect-options.html#running-sect-help-option) for reference (or simply execute `mvn -h`).
e know that a project's dependencies are declared in pom.xml. Apache Maven uses concept of repository to hold JAR files. There are two kinds of repository, local repository and remote repository. You can define this in settings.xml on maven/conf directory or pom.xml itself. When we kick off Maven build process by executing mvn install command, it first search for dependency JAR in local repository, if it found there it uses, otherwise it goes to remote repository to download corresponding version of JAR file and stores into local repo as well. There is one more thing, which is worth remember is type of dependency. If you have included a SNAPSHOT JAR e.g. 1.2-SNAPSOT as part of your dependency, opposite to regular stable version 1.2
