基于注释，在库中找不到字体文件

Answer 1

为了完整起见，我在这里添加保罗·泰勒的答案：

Openjdk 依赖于我没有安装的系统字体，但我 发现在 JRE 的 lib 文件夹中创建一个字体文件夹，然后只是 将一些字体复制到其中解决了问题

看这里： stackoverflow.com/questions/43144517/...

Answer 2

只需在Dockerfiel中添加以下内容

RUN apk add --no-cache fontconfig ttf-dejavu

或者，如果是机器，则执行以下命令

apk add --no-cache fontconfig ttf-dejavu
