### Verify With Code Sample
This case simulates a multi-module project that includes one of the following services and a contract directory that holds standard contracts.  
This case will use the standard contract to verify the contract of the current project and output the verification result to the console

### Prerequisites
You will need:
1. [JDK 1.8](http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html)
2. [Maven 3.x](https://maven.apache.org/install.html)

### Step1: Configure plugin
In the pom.xml file in the root directory of the current sample project, add the configuration of the toolkit-maven-plugin plugin as follows.
```xml
<plugin>
    <groupId>org.apache.servicecomb.toolkit</groupId>
    <artifactId>toolkit-maven-plugin</artifactId>
    <version>0.3.0-SNAPSHOT</version>
    <configuration>
        <!-- Set to 'code' to resolve the current project. Set to 'contract' to resolve the contract file for the specified path.If not set, the default is 'code' -->
        <sourceType>code</sourceType>
        <!-- Sample contract file path, must be set -->
        <destinationContractPath>./contract</destinationContractPath>
    </configuration>
</plugin>
```

### Step2: Running Demo
Execute the following maven command on the command line
```
mvn toolkit:verify
```

### Step3: Output Result
The result of the verification is output directly on the console
```
[INFO] Contract is not matched, difference is as follows
[INFO] ./contract/GreetingController.yaml vs /opt/sunlisen/workspace/servicecomb-toolkit/samples/verify-with-code-sample/target/tmp-contract/2244468406394280775/GreetingController.yaml
