Maven PITest错误“在当前项目和插件组中找不到前缀“org.PITest”的插件”

Question

我需要使用PITest进行突变测试，但我很难尝试通过Maven安装它，当我尝试运行PIT以执行突变和测试用例时，我在cmd中收到此错误：

“在当前项目和插件组中未找到前缀“org.pitest”的插件”

有人能帮我解决这个问题吗？

我的代码：

package com.mateus;

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Codigo {

    public boolean verify(String word){
        String regex = "^[a-zA-Z0-9_$]+$";
        Pattern pattern = Pattern.compile(regex);
        Matcher matcher = pattern.matcher(word);
        if(word.substring(0, 1).matches("[0-9]")){
            return false;
        }
        return matcher.matches();
    }

}

我的测试：

package com.mateus;

import static org.junit.Assert.*;

import org.junit.Test;

public class CodigoTest {
    Codigo c = new Codigo();
    @Test
    public void test() {
        assertEquals(true, c.verify("teste"));
    }
    @Test
    public void test2() {
        assertEquals(false, c.verify("1teste"));
    }
    @Test
    public void test3() {
        assertEquals(false, c.verify("tes@te"));
    }

}

Answer 1

你必须这样使用插件。

<plugin>
    <groupId>org.pitest</groupId>
    <artifactId>pitest-maven</artifactId>
    <version>1.4.10</version>
    <configuration>
        <targetClasses>
            <param>com.mateus*</param>
        </targetClasses>
        <targetTests>
            <param>com.mateus*</param>
        </targetTests>
    </configuration>
</plugin>

EIDT：请使用1.4.10版本，而不是最新版本，请参见下面的参考链接。

https://pitest.org/quickstart/maven/

它也可以在maven central中找到，您可以查看此链接。
