。

安装步骤以重制

这些步骤包含在Java 8的Ubunto 18.04下也应该安装Jenkins的过程？在Ubuntu 18.04.04下也是如此吗？

 sudo add-apt-repository ppa:webupd8team/java
    sudo apt install oracle-java8-installer
    wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add -

    sudo apt install jenkins

Answer 1

您安装了OracleJDK，但Jenkins找到了OpenJDK

尝试

sudo update-alternatives --config java

Answer 2

感谢@GaRaOne，选择正确的 Java 版本对我有帮助：

$ sudo update-alternatives --config java 
There are 2 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                            Priority   Status
------------------------------------------------------------

  1            /usr/lib/jvm/java-11-openjdk-amd64/bin/java      1111      manual mode
* 2            /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java   1081      manual mode
