[QueryDSL] STS에서 Gradle 사용 시 QueryDSL QClass 생성 설정

1. build.gradle

/* Eclipse 설정 시작 ----------------------------*/
def querydslDir =  "src/main/generated"

querydsl {
	library = "com.querydsl:querydsl-apt"
    jpa = true
    querydslDefault = true
    querydslSourcesDir = querydslDir
}
//에디터 설정
sourceSets {
	main { 
		java {
			srcDirs = ['src/main/java', querydslDir] 
		}
	}
}
//컴파일 클래스 패스에 넣음.
configurations {
    querydsl.extendsFrom compileClasspath
}
//어노테이션 프로세서와 맞물려서 빌드시 생성
compileQuerydsl {
    options.annotationProcessorPath = configurations.querydsl
}

/* Eclipse 설정 종료 ----------------------------*/
