我正在寻找ini文件格式的官方规范/定义.

我在维基百科旁边找不到任何东西.

使用扩展属性配置 Exec-Task 时遇到问题。

问题

我的 Exec-Task 的配置依赖于扩展中定义的 String-Property。不幸的是，在配置 Exec-Task 时，该属性尚未设置。这导致TaskCreationException：

Could not create task ':myTask'.
org.gradle.api.internal.tasks.DefaultTaskContainer$TaskCreationException: Could not create task ':myTask'.
    ...
Caused by: org.gradle.api.internal.provider.MissingValueException: Cannot query the value of extension 'myConfig' property 'command' because it has no value available.
    at org.gradle.api.internal.provider.AbstractMinimalProvider.get(AbstractMinimalProvider.java:86)

例子

Could not create task ':myTask'.
org.gradle.api.internal.tasks.DefaultTaskContainer$TaskCreationException: Could not create task ':myTask'.
    ...
Caused by: org.gradle.api.internal.provider.MissingValueException: Cannot query the value of extension 'myConfig' property 'command' because it has no value available.
    at org.gradle.api.internal.provider.AbstractMinimalProvider.get(AbstractMinimalProvider.java:86)

问题似乎在于myConfig.command.get()它规避了惰性评估。 …

minifyEnabled true在我的 gradle 中设置时，我在启动我的应用程序时收到NullPointerException：

我有一个基于健康检查图像的图像。就我而言，它是 oracle 数据库映像container-registry.oracle.com/database/express:21.3.0-xe。

但是，当我使用 podman 构建映像时，它不再包含应从基础映像继承的运行状况检查。

当您查看图像时，您可以看到该图层podman history（见下文）。但是当您从此映像创建容器时，podman 和 docker 都不会显示健康状态。

奇怪的是，当使用 docker而不是 podman构建映像时，它会按预期工作。我希望无论是由 podman 还是 docker 构建，都没有什么区别。
