我想在eclipse氧气内部的分级项目中使用java9。当我跑步时:
Run as> Gradle Test on GreeterTest.java使用以下代码:
package hello.test;
import static org.junit.jupiter.api.Assertions.*;
import org.junit.jupiter.api.Test;
import hello.Greeter;
class GreeterTest {
@Test
void test() {
Greeter greeter = new Greeter();
assertEquals("Hello world", greeter.sayHello());
}
}我测试的班级是:
package hello;
public class Greeter {
public String sayHello() {
return "Hello world!";
}
}我得到了错误信息
无法针对平台:'Java 9‘使用工具链:'JDK 8 (1.8)’。
我的eclipse.init是

我已经在Build.Gradle中设置了编译参数。

}我该怎么做才能让这一切开始?

在我看来,这是Gradle版本的问题。(Gradle和Java 9兼容性问题)。
您需要将包装器升级到4.3.1,cli ref:
# upgrade Gradle to 4.3.1
gradle wrapper --gradle-version 4.3.1 # not ./gradlew如果成功的话请告诉我。

我改变了java_home并升级了Gradle。现在起作用了。

我之所以面临这个问题,是因为在设置>构建工具> " Gradle“部分的IntelliJ思想中,Gradlje使用了不正确的Java版本。所以我指定使用JAVA_HOME,它解决了这个问题。
