나는 Debian 9에 openjdk 9를 설치하려고 노력했고 모든 것이 해당 설치를 가리키도록 했습니다. 그러나 뭔가가 꺼져 있고 java터미널의 기본 명령이 가리키는 위치를 업데이트하고 싶지 않습니다 .
간단한 방법으로 openjdk9를 설치했습니다.sudo apt-get install openjdk-9-jre openjdk-9-jdk
내가 실행하면 readlink $(which java)다음을 가리킨다./etc/alternatives/java
내가 실행하면 readklink /etc/alternatives/java다음을 가리킨다./usr/lib/jvm/java-9-openjdk-amd64/bin/java
하지만 가장 이상한 점은 한 번 실행하면 터미널에서 실행할 때 얻는 결과가 정확히 무엇인지 가리킨다는 readlink -f $(which java)것입니다 ./usr/lib/jvm/java-8-openjdk-amd64/jre/bin/javajava -version
openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-1-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)
심볼릭 default-java링크는 openjdk 8도 가리킵니다.
그러나 javac -version터미널에서는 올바르게 보입니다.
javac 9.0.1
update-alternativesjava다음과 잘 어울리는 것 같습니다 javac:
$ sudo update-alternatives --config java
There are 2 choices for the alternative java (providing /usr/bin/java).

java명령이 시스템의 나머지 부분과 일치하도록 할 수 없는 이유를 아는 사람이 있습니까 ? 아니면 다음에 무엇을 시도할지에 대한 아이디어가 있나요?
매우 감사합니다.
