java - install4j 无法从著名的 OpenJDK 提供商处下载 JDK 文件

Question

Install4j 允许用户使用 json 属性选择用于自动下载的 JDK:

 <jreBundles jdkProviderId="Liberica" release="OpenJDK 11.0.6+10">

在我的桌面上，我可以很好地空运行，还可以从 bellsoft 获取 jdk-

但是，当我在服务器上运行空运行时，出现以下错误并且无法获取 jdk。我可以在浏览器中从网站在线下载它而不会出现问题，但不能使用 Install4j GUI。

Answer 1

如果构建服务器无法连接到 JDK 提供者的服务器，您可以通过将相关目录转移到

$HOME/.install4j/jres/generated 

从您的开发机器到构建机器，则无需下载。这假设您已经为您的开发机器上的所有媒体文件运行了构建，因此所有 JRE 包都已生成。
