java - Gradle找不到JDK

Question

我使用以下配置创建了一个 gradle 项目:

group '...'
version '0.0'

apply plugin: 'java'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

test {
    useTestNG()

    beforeTest { descriptor ->
        logger.lifecycle("Running test: " + descriptor)
    }
}

当我执行“gradle build”时，出现以下错误消息:

Cannot find System Java Compiler. Ensure that you have installed a JDK (not just a JRE) and configured your JAVA_HOME system variable to point to the according directory.

这很奇怪，因为我设置了 $JAVA_HOME:

✗ echo $JAVA_HOME
/usr/lib/jvm/java-8-oracle
✗ $JAVA_HOME/bin/javac
Usage: javac <options> <source files>
where possible options include:

我找到了解决方案。

为了解决这个问题，我只需执行:

./gradlew build

这成功了。
