Eclipse 2021-06 이상 lombok 설정

 1. lombok 설정 

lombok은 VO에 자동으로 Setter, Getter를 생성해주는 것이다.

 

의존성 추가

https://mvnrepository.com 에서 lombok을 검색 후 원하는 버전을 선택한다. 

메이븐 프로젝트의 경우엔 pom.xml에, gradle일 경우엔 build.gradle에 소스를 복사하여 붙여넣는다.

https://projectlombok.org/  => download에서 프로그램을 설치한다.

java -jar lombok.jar

lombok.jar를 실행시켜서 Specify location을 클릭하여 eclipse.exe 를 찾아 추가 후 install을 클릭하여 설치한다.

eclipse.ini에 아래가 추가된 것을 알 수 있다.

-javaagent:D:\eclipse-jee-2021-06\lombok.jar

2. Eclipse 2021-06 에서 lombok 사용시 Unable to make protected... 에러 해결

Unable to make protected final java.lang.Class java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int) 

throws java.lang.ClassFormatError accessible: module java.base does not "opens java.lang" to unnamed module @4eb63dc8

일단 이클립스를 종료 하고 eclipse 설치폴더의 eclipse.ini 파일을 찾아갑니다.

그러고 제일 아래 -javaagent:D:\eclipse-jee-2021-06\lombok.jar 밑에 두줄의 내용을 붙이고 저장합니다.

--illegal-access=warn

--add-opens java.base/java.lang=ALL-UNNAMED

대략 이런 에러가 발생했을 경우.
POM.xml을 확인해보면

<project xmlns="http://maven.apache.org/POM/4.0.0"                 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  </dependencies>
  <build>
    <finalName>hello</finalName>
   </build>
 </project>
이렇게 되어 있을 것이고,
해결방법은 POM.xml에
<dependency>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>2.4.3</version>
</dependency>

이런식으로 디펜던시를 추가해주면 된다.(현재 날짜 기준으로 최신버전인 3.2.1은 되지 
않는다.)

이렇게 작성해준 뒤에, 

1. 프로젝트 우클릭 > Run As > Maven Install

2. 이클립스 프로젝트 탐색기에서 해당 프로젝트 클릭 후 F5(새로고침)

3. 프로젝트 우클릭 > Maven > Update Project 

끝!

Argument 'getContext()' might be null

프래그먼트  |  Android 개발자  |  Android Developers

A Fragment represents a behavior or a portion of user interface in an Activity. You can combine multiple fragments in a single activity to build a multi-pane UI and reuse a fragment in multiple activities. You can think of a fragment as a modular section…

developer.android.com

Fragment 생명주기에 보면, 다음과 같이 주의사항이 표시.

따라서 안전하게 

다음과 같이 onAttach에서 context 와 activity를 복사해두자.

    @Override
    public void onAttach(Context context) {
        mContext = context;
        if (context instanceof Activity) {
            mActivity = (Activity)context;
        }
        super.onAttach(context);
    }
    
    
    // detach에서는 변수 clearing 해주기 leak방지
    @Override
    public void onDetach() {
        mActivity = null;
        mContext = null;
        super.onDetach();
    }
