[원인]
maven 도구의 jansi가 console에서 Ansi를 사용하기 위해 시스템에 접근해서 해당 이슈가 발생하는 것으로 판단됨
maven/3.9.9/libexec/lib/jansi-2.4.1.jar
[해결방안]
maven 3에서:
# MAVEN_OPTS 지정
export MAVEN_OPTS="--enable-native-access=ALL-UNNAMED"
zsh에 기본으로 적용하려면 ~/.zshrc 에 위의 설정을 적용하면 기본 쉘환경에 적용됨
현재 열려있는 쉘에 적용하려면 source ~/.zshrc 를 실행하여 적용
maven 4에서:
해당 이슈가 Apache Maven 프로젝트에 보고되어 https://issues.apache.org/jira/browse/MNG-8399?page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel&focusedCommentId=17939366 에서 찾을 수 있고, jansi는 maven 4에서 더이상 이슈가 되지 않는다는 4일전에 작성된 댓글에서 확인이 가능합니다
maven 4에서는 "--enable-native-access=ALL-UNNAMED" 옵션 지정이 필요없을 것으로 보입니다
하지만 아직 brew에는 maven 3.9.9까지만 배포되고 있습니다
