我正在以Debian Stretch作为来宾运行WSL。我已经安装了openjdk-11-jdk。我也有一个非常好的gradle Spring Boot应用程序（由Spring Boot Initializr生成的默认值）。
./ gradlew构建最初会给出错误：

在使用openjdk-11时，我已经看到了有关证书问题的参考，我怀疑这是问题的根源，但是我无法找到一种明确的方法来使这部分工作正常进行。
答案 0 :(得分：0)
潜在问题似乎与this bug in the ca-certificates-java package有关，因此显然有更好的解决方案。
就目前而言，我可以按照以下方法解决此问题： 1.在Windows主机上，我下载了Oracle Java 11 JDK。 2.我从Powershell using these instructions中提取了存档。使用适合您的任何方法。 3.我将path \到\ where \ you \ extracted \ jdk-11.0.2 \ lib \ security \ cacerts复制到wsl可以访问的目录中，在我的情况下是/ c / Users / James Lafferty / Desktop / my_project。
然后我运行了以下命令：
sudo mv /etc/ssl/certs/java/cacerts /etc/ssl/certs/java/cacerts.bk
sudo mv /etc/ssl/certs/java/cacerts /etc/ssl/certs/java/cacerts.bk
sudo mv cacerts /etc/ssl/certs/java/cacerts
sudo chmod --reference=/etc/ssl/certs/java/cacerts.bk /etc/ssl/certs/java/cacerts
sudo chown --reference=/etc/ssl/certs/java/cacerts.bk /etc/ssl/certs/java/cacerts
完成所有这些操作后，我将s放回https，./gradlew build的工作就像一个魅力。
