java我的POM怎么了?“解析表达式..检测到递归表达式循环”

我有一些TestNG SuiteXML文件,其中包含如下运行时参数:-

 <!--SERVER AND TARGET PARAMS-->
    <parameter name="environment" value="${environment}"/>
    <parameter name="port" value="${port}"/>

我的POM看起来是这样的:

<?xml version="1.0" encoding="UTF-8"?>

http://maven.apache.org/xsd/maven-4.0.0.xsd“>; 4.0.0

我的错误是:

[ERROR]     Resolving expression: '${environment}': Detected the following recursive expression cycle in 'environment': [environment] -> [Help 2]
[ERROR]     Resolving expression: '${port}': Detected the following recursive expression cycle in 'port': [port] -> [Help 2]

我是不是很蠢?也许,我毕竟只是一名测试人员,而且大脑非常小。有人能帮我排除故障吗?我的POM看起来蓬松吗

它不会将我所需的JAR下载到本地。m2,直到我能修好它——我已经试着吹走了。m2和mvn安装等。。。。没有欢乐

    你的错误来自这一部分:

    <properties>
        <sl4j.version>1.7.7</sl4j.version>
        <suiteFile>${suiteFile}</suiteFile>
        <environment>${environment}</environment>
        <port>${port}</port>
    </properties>
    

    当您使用${port}时,Maven会在<port>X</port>中查找值,这里的X=${port}等等。。。这就是为什么这里有一个递归问题

  2. # 2 楼答案

    我不确定,因为我只有时间快速查看,但定义一个属性,然后将该属性分配给它自己,这是我认为您所做的,也是导致错误的原因

    你不能只在pom中使用${suiteFile},而不在<properties></properties>中定义它吗

    或者可以在pom中使用其他属性名称? 例如:

     <properties>
            <suiteFile1>${suiteFile}</suiteFile>
            <environment1>${environment}</environment>
            <port1>${port}</port>
        </properties>
    

    在你的pom中使用这些

    我今天遇到了同样的问题。更有趣的是,那是在我几分钟前成功执行了同一个项目之后。事实证明,构建配置在命令(clean package等)被写入概要文件时出错
    这是一个愚蠢的错误,但却让我花了一些时间,而它之所以能更早地工作,是因为我手动输入了命令,而不是使用保存的构建配置
