java Corda示例在尝试运行节点时失败
我读过a similar issue，但我的环境不同
我已经克隆了Corda样本，并确保我拥有Java 8（更新301）和Gradle 5.6.4：
cordapp-example % java -version
java version "1.8.0_301"
Java(TM) SE Runtime Environment (build 1.8.0_301-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.301-b09, mixed mode)
cordapp-example % gradle -version

Gradle 5.6.4

然而，当我遵循“运行示例Cordapp”tutorial时，我在runnodes步骤失败：

仔细检查三个未通过的选项卡中的第一行后，我们看到：
... "/Library/Java/JavaVirtualMachines/jdk-11.0.10.jdk/Contents/Home/bin/java" ...
我的OS X上也安装了这个Java 11，但为什么要使用它呢！？
java -version，如上所示，指向1.8u301
cordapp-example % echo $JAVA_HOME

就我个人而言，我不知道为什么JDK11会被选中。。是否需要将其从系统中删除
以后编辑：
当我从cordapp示例目录运行./build/nodes/runnodes时，会发生此问题。如果我转到build/nodes并在那里运行java -jar runnodes.jar，一切正常，正如预期的那样
# 1 楼答案
答案就在
runnodes脚本文件中：第11行被执行（与第13行相反），它使用
/usr/libexec/java_home，这在我的情况下（以及许多其他人的情况下，从我在网上能找到的判断…）将指向安装的最新JDK。这就是JDK 11，Corda与之不兼容只需确保你不使用那个，而是使用JDK 8更新131
