我正在关注一个小测试脚本并为其提供第一段代码以使其变为绿色。代码是java,测试与java混在一起。 Java是Mac OSX“El Capitan”上的版本“1.8.0_60”。 gradle
是版本2.8。
使用gradle build
后,显示错误:
$ gradle build
:compileJava
/Users/rsalazar/exercism/java/etl/src/main/java/Etl.java:1: error: package com.google.common.collect does not exist
import com.google.common.collect.ImmutableMap;
^
/Users/rsalazar/exercism/java/etl/src/main/java/Etl.java:9: error: cannot find symbol
return ImmutableMap.of("a", 1);
^
symbol: variable ImmutableMap
location: class Etl
2 errors
:compileJava FAILED

BUILD FAILED
Total time: 2.597 secs
以下是build.gradle
文件:
apply plugin: "java"
apply plugin: "eclipse"
apply plugin: "idea"
repositories {
mavenCentral()
}
dependencies {
testCompile "junit:junit:4.10"
testCompile "org.easytesting:fest-assert-core:2.0M10"
testCompile "com.google.guava:guava:16+"
}
以下是测试:(EtlTest.java
)
import com.google.common.collect.ImmutableMap;
import org.junit.Test;
import java.util.Arrays;
import java.util.List;
import java.util.Map;
import static org.fest.assertions.api.Assertions.assertThat;
public class EtlTest {
private final Etl etl = new Etl();
@Test
public void testTransformOneValue() {
Map<Integer, List<String>> old = ImmutableMap.of(1, Arrays.asList("A"));
Map<String, Integer> expected = ImmutableMap.of("a", 1);
assertThat(etl.transform(old)).isEqualTo(expected);
}
}
以下是测试中的代码:(Etl.java
)
import com.google.common.collect.ImmutableMap;
import java.util.Arrays;
import java.util.List;
import java.util.Map;
public class Etl {
public Map<String, Integer> transform(Map <Integer, List<String>> from) {
return ImmutableMap.of("a", 1);
}
}
我不是在寻求测试通过的帮助。只是帮助用gradle编译测试。我很遗憾地说,在使用提供的错误消息进行编译时我遇到了困难。我在网上找不到任何帮助。非常感谢!
答案 0 :(得分:6)
由于您需要ImmutableMap
来编译源代码(不仅是测试源代码),您还需要更改此行:
testCompile "com.google.guava:guava:16+"
到此:
compile "com.google.guava:guava:16+"
它将在编译时为源代码提供guava,从而解决问题。
