背景介绍:因langchain4j最新版本(>=0.36.0)(Min JDK version has been upgraded to 17)需JDK17起,故直接使用Amazon Corretto JDK 21作为基础镜像。
在使用 JDK21 进行开发或运行相关应用时,有时会遭遇令人困扰的问题。今天运行 java -jar xxx.jar时出现 "Error: An unexpected error occurred while trying to open file xxx.jar" 这样的错误提示,给开发进程带来阻碍。接下来我们将逐步重现该过程以及如何绕过该问题。
容器环境
宿主机:CentOS Linux release 7.6.1810 (Core)
Docker版本:
containerd.io.x86_64 1.2.13-3.2.el7 @docker-ce-stable
docker-ce.x86_64 3:19.03.12-3.el7 @docker-ce-stable
docker-ce-cli.x86_64 1:19.03.12-3.el7 @docker-ce-stable
Docker-Compose:docker-compose version 1.26.2, build eefe0d31
镜像构建脚本
直接复制 corretto-docker-debain-21 的脚本
Dockerfile
FROM debian:buster-slim
ARG version=21.0.5.11-1
# In addition to installing the Amazon corretto, we also install
# fontconfig. The folks who manage the docker hub's
# official image library have found that font management
# is a common usecase, and painpoint, and have
# recommended that Java images include font support.
#
# See:
# https://github.com/docker-library/official-images/blob/master/test/tests/java-uimanager-font/container.java

构建工程
shell
mvn clean package
容器内运行工程
什么问题引起?
暂时未知,只好换旧版的JDK21(21.0.0.35.1)试试
安装完成后验证版本
shell
root@e3bd319b01b7:/home# java -version
openjdk version "21" 2023-09-19 LTS
OpenJDK Runtime Environment Corretto-21.0.0.35.1 (build 21+35-LTS)
OpenJDK 64-Bit Server VM Corretto-21.0.0.35.1 (build 21+35-LTS, mixed mode, sharing)
运行工程
至此绕过 Error: An unexpected error occurred while trying to open file Sample-1.0-SNAPSHOT-exec.jar 的问题。
最后,若你知道如何解决该问题,请留言。
