java - 找不到 Gradle 构建工具.jar

Question

我正在尝试在 RHEL EC2 机器中构建 spring boot 应用程序。我在 gradle build 中找不到“tools.jar”

readlink -f $(which java)
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-2.el8_1.x86_64/jre/bin/java

export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-2.el8_1.x86_64/jre
echo $JAVA_HOME
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-2.el8_1.x86_64/jre

但是当我尝试构建时，我遇到了以下错误

$gradle build
 > Task :compileJava FAILED

 FAILURE: Build failed with an exception.

 * What went wrong:
 Execution failed for task ':compileJava'.
 > Could not find tools.jar. Please check that /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09- 
 2.el8_1.x86_64/jre contains a valid JDK installation.

 * Try:

 log output. Run with --scan to get full insights.

我安装了 jdk 并运行了 $yum install java-1.8.0-openjdk-devel。使用相同的 jre 路径成功构建后
