修改gradle.build文件如下：
apply plugin: 'java'
sourceCompatibility = 1.7 // 设置java编译版本兼容1.7
version = 0.1 //定义项目版本
jar {
manifest {
attributes 'Main-Class': 'com.manning.gia.todo.ToDoApp' // 设置Main class
}
}
# 重新gradle build
$ gradle build
#重新执行 gradle properties
sourceCompatibility: 1.7

## 查看生成的jar 包，名字如下：
gradle-0.1.jar
改变项目默认结构,新的gradle.build文件如下：
