gradle compileJava 错误 : package org. junit 不存在

Question

我正在尝试使用 gradle 实现一个简单的 junit 测试，并在运行时遇到以下问题 gradle test :

:compileJava
/Users/wogsland/Projects/gradling/src/test/CalculatorTest.java:1: error: package org.junit does not exist
import static org.junit.Assert.assertEquals;
                       ^
/Users/wogsland/Projects/gradling/src/test/CalculatorTest.java:1: error: static import only from classes and interfaces
import static org.junit.Assert.assertEquals;
^
/Users/wogsland/Projects/gradling/src/test/CalculatorTest.java:2: error: package org.junit does not exist
import org.junit.Test;
                ^
/Users/wogsland/Projects/gradling/src/test/CalculatorTest.java:5: error: cannot find symbol
  @Test
   ^
  symbol:   class Test
  location: class CalculatorTest
/Users/wogsland/Projects/gradling/src/test/CalculatorTest.java:9: error: cannot find symbol
    assertEquals(6, sum);
    ^
  symbol:   method assertEquals(int,int)
  location: class CalculatorTest
5 errors
:compileJava FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':compileJava'.
Compilation failed; see the compiler error output for details.

所以我有这个 build.gradle文件:

apply plugin: 'java'

dependencies {
    testCompile 'junit:junit:4.12'
}

sourceSets {
  main {
    java {
      srcDir 'src'
    }
  }
}

和 CalculatorTest.java :

import static org.junit.Assert.assertEquals;
import org.junit.Test;

public class CalculatorTest {
  @Test
  public void evaluatesExpression() {
    Calculator calculator = new Calculator();
    int sum = calculator.evaluate("1+2+3");
    assertEquals(6, sum);
  }
}

但是当我将它包含在依赖项中时，我无法弄清楚为什么它没有找到 junit。

所以显然我需要添加一个 compile依赖，然后还声明 repositories .我的新 build.gradle成功运行测试:

apply plugin: 'java'

repositories { jcenter() }
dependencies {
    testCompile 'junit:junit:4.12'
    compile 'junit:junit:4.12'
}

sourceSets {
    main {
        java {
            srcDir 'src'
        }
    }
}
