我试图向我的 Jenkins 主人启动一个新的奴隶，但我收到以下错误:

我认为主要问题是: 引起原因:java.io.IOException:无法找到登录表单。 但是我似乎无法在网上找到有关此问题的任何信息。 我在从属设备上安装了 JDK 和 JRE，但是当我启动从属设备时，它仍然尝试下载 JDK，我不知道为什么..
最佳答案
这与 New Oracle website prevents the JDKInstaller to download binaries from archives 。 甲骨文不久前更改了他们的网站。
您必须下载 Java 并将其单独安装在您的从属设备上。 (例如:sudo apt-get install default-jre)
这样就可以了:-D。
