java - 无法在CentOS 7上执行java程序

Question

按照本指南测试 JIRA 性能:

https://github.com/atlassian/jira-performance-tests/blob/master/docs/tests/ON_PREMISE.md

安装JAVA:

$ sudo yum install java-11-openjdk-devel

使用这种方式得到安装的JAVA路径:

$ update-alternatives --config java
java-11-openjdk.x86_64 (/usr/lib/jvm/java-11-openjdk-11.0.5.10-0.el7_7.x86_64/bin/java)

将 /usr/lib/jvm/java-11-openjdk-11.0.5.10-0.el7_7.x86_64/bin/java 设置为 ~/.bash_profile 作为环境变量:

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-11.0.5.10-0.el7_7.x86_64/bin/java

源文件:

$ source ~/.bash_profile

检查JAVA_HOME:

$ echo $JAVA_HOME
/usr/lib/jvm/java-11-openjdk-11.0.5.10-0.el7_7.x86_64/bin/java

从 JIRA 测试路径运行测试命令:

$ cd jira-performance-tests/examples/btf-test
$ ./mvnw verify

出现错误:

Error: JAVA_HOME is not defined correctly.
  We cannot execute /usr/lib/jvm/java-11-openjdk-11.0.5.10-0.el7_7.x86_64/bin/java/bin/java

为什么？

Answer 1

通常给出JAVA_HOME，而不给出/bin/java。 我建议将 JAVA_HOME 更改为 /usr/lib/jvm/java-11-openjdk-11.0.5.10-0.el7_7.x86_64。
