gradle Spring 引导应用程序的包装器在 Java 8、Gradle 3 上失败：找不到 cacerts

Question

我在使用 gradle wrapper 命令创建 gradlew 文件时遇到了问题。我的设置很简单： Ubuntu 14.04 + Java 8 (openjdk version "1.8.0_91") + Gradle 3.0

使用的教程：

这个问题的奇怪之处在于 gradle wrapper 失败的原因是因为 cacerts 文件或目录显然丢失了 - 但事实并非如此（请参阅下面的 'check cacerts file/directory'）。虽然 - 请让我知道这是否是问题所在 - 它是 link 而不是实际的 file/dir。我不知道是否还有其他问题，因为丢失的 cacerts 错误似乎是在一连串错误的末尾，但是任何调试此问题的帮助将不胜感激。

下面列出了我的相关文件和输出。

您可能遇到了一个错误，导致证书的符号链接悬空，如报告的那样 here and here。一种建议的解决方案是重新安装 ca-certificates-java 软件包。像这样：

$ sudo dpkg --purge --force-depends ca-certificates-java
$ sudo apt-get install ca-certificates-java
