java - 使用 maven 运行 testng 套件 xml 时 maven-surefire-plugin 中的 NullPointerException

Question

当我使用 maven 运行我的 testng 套件 xml 而套件标签中没有 parallel="tests"时，我遇到异常。

当我使用 parallel="tests"运行它时，它工作正常。另外，如果我在没有 parallel="tests"的情况下从 eclipse“作为 testng 测试运行”运行我的 testng 套件 xml，它工作正常。请帮忙。

我的套件 xml-

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >

<suite name="Filters API" parallel="tests">
    <test name="Filters Test">
        <classes>
            <class name="com.api.testng.modules.filters.FiltersTests"/>
        </classes>
    </test>
</suite>
