无法设置 Jenkins 的 JAVA_HOME 路径

Question

My Jenkins is hosted on a Linux server but when I type echo $JAVA_HOME on Linux it is empty but my Jenkins stated "/usr/lib/jvm/java-8-openjdk-amd64"

Attempt method:
Set JDK in Global Tool Configuration
-Name JAVA
-JAVA_HOME /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.242.b08-0.el7_7.x86_64
->ERROR:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.242.b08-0.el7_7.x86_64 is not a directory on the Jenkins master (but perhaps it exists on some agents)

-Add JDK
-Tick Install automatically -Name JAVA
-Add Installer, Extract .zip/ .tar.gz
-Label JAVA
-Download URL for binary " https://corretto.aws/downloads/latest/amazon-corretto-8-x64-linux-jdk.tar.gz "

unknown error: cannot find Chrome binary Build info: version: '3.141.59', revision: 'e82be7d358', time: '2018-11-14T08:17:03' System info: host: '8f5b40c32460', ip: '172.18.0.2', os.name: 'Linux', os.arch: 'amd64', os.version: '3.10.0-229.4.2.el7.x86_64', java.version: '1.8.0_121' Driver info: driver.version: ChromeDriver

Linux cmd
javac -version javac 1.8.0_242 java -version openjdk version "1.8.0_242" OpenJDK Runtime Environment (build 1.8.0_242-b08) OpenJDK 64-Bit Server VM (build 25.242-b08, mixed mode)

Answer 1

Since you already have java installed in the jenkins instance, you just have to point the configuration to the right directory (Fill in the JAVA_HOME property below).

Seems like " /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.242.b08-0.el7_7.x86_64 " is not the correct directory. You can find your JDK location using the following command:

readlink -f $(which java)

Answer 2

转到管理 Jenkins 然后全局工具位置搜索 Java 并将变量名称添加为 JAVA_HOME 并将值添加为“pathof Jdk/bin/”保存它。
