Google Java Format +验证Google Java格式组合不工作Gradle

Question

我是gradle的新手；我只是将它添加到我的main repository中，看看它是如何工作的。下面是我的build.gradle文件的外观：

plugins {
    id 'java'

    id 'application'

    id 'com.github.sherter.google-java-format' version '0.8'
}

repositories {
    jcenter()
}

dependencies {
    compile fileTree(include: ['jblas-1.2.4.jar'], dir: 'libs')

    implementation 'com.google.guava:guava:28.1-jre'

    testImplementation 'junit:junit:4.12'
}

application {
    mainClassName = 'sorting.bubblesort.BubbleSort'
}

如您所见，我应用了一个名为google-java-format的插件。然而，我在这两个任务中遇到了一个问题：

googleJavaFormat
verifyGoogleJavaFormat

我可以运行googleJavaFormat，它显示它运行成功。然而，在那之后，verifyGoogleJavaFormat说它的格式不正确。下面是唯一一个格式不正确的文件：

package DataStructures.MinPriorityQueue;

import datastructures.minpriorityqueue.MinHeap.MinHeap;
import org.junit.Test;

import java.util.Arrays;
import java.util.HashSet;
import java.util.PriorityQueue;

import static org.junit.Assert.*;

public class MinHeapTest {
  @Test
  public void containsTest() {
    for (int i = 0; i < 10000; i++) {
      HashSet<Integer> set = new HashSet<>();
      MinHeap<Integer> heap = new MinHeap<>(Integer::compare);
      for (int j = 0; j < 1000; j++)
        if (Math.random() >= 0.5) {
          set.add(j);
          heap.add(j);
        }
      for (Integer integer : set) assertTrue(heap.contains(integer));
    }
  }

  @Test
  public void isEmptyTest() {
    for (int i = 0; i < 100; i++) {
      MinHeap<Integer> heap = new MinHeap<>(Integer::compare);
      assertTrue(heap.isEmpty());
      int randomAmount = 1 + (int) (Math.random() * 1000);
      for (int j = 0; j < randomAmount; j++) heap.add((int) (Math.random() * 1000));
      assertFalse(heap.isEmpty());
    }
  }

  @Test
  public void extractMinTest() {
    for (int i = 0; i < 1000; i++) {
      PriorityQueue<Integer> priorityQueue = new PriorityQueue<>(Integer::compare);
      MinHeap<Integer> heap = new MinHeap<>(Integer::compare);
      for (int j = 0; j < 1000; j++)
        if (Math.random() >= 0.5) {
          priorityQueue.add(j);
          heap.add(j);
        }
      assertEquals(priorityQueue.poll(), heap.extractMin());
    }
  }

  @Test
  public void chainedExtractMinTest() {
    for (int i = 0; i < 1000; i++) {
      int[] toAdd = new int[1000];
      MinHeap<Integer> heap = new MinHeap<>(Integer::compare);
      for (int j = 0; j < toAdd.length; j++) {
        toAdd[j] = (int) (Math.random() * 1000);
        heap.add(toAdd[j]);
      }
      int[] sorted = toAdd.clone();
      Arrays.sort(sorted);
      int[] heapValues = new int[1000];
      for (int j = 0; j < heapValues.length; j++) heapValues[j] = heap.extractMin();
      assertArrayEquals(sorted, heapValues);
    }
  }

  @Test
  public void decreaseKeyTest() {
    for (int i = 0; i < 1000; i++) {
      MinHeap<Integer> heap = new MinHeap<>(Integer::compare);
      PriorityQueue<Integer> queue = new PriorityQueue<>(Integer::compare);
      for (int j = 0; j < 1000; j++) heap.add(j);
      for (Integer j : heap) heap.decreaseValue(j, (int) (Math.random() * j));
      for (Integer j : heap) queue.add(j);
      while (!heap.isEmpty()) assertEquals(queue.poll(), heap.extractMin());
    }
  }
}

即使在我对这个文件运行googleJavaFormat之后，verifyGoogleJavaFormat也没有成功。为什么会发生这种情况？

Answer 1

好了，我得到答案了。因为我使用的是Intellij，所以它在导入中移动。例如，每当它在导入中看到星号*时，它就会将其展开。我刚刚打开了File | Settings | Editor | General | Auto Import，并取消选中optimize imports on the fly。
