Maven项目编译

Question

我正在尝试通过运行"mvn clean compile“来编译maven项目

我得到的错误如下：

[INFO] Scanning for projects...
[ERROR] [ERROR] Some problems were encountered while processing the POMs:
[ERROR] Resolving expression: '${xmlName}': Detected the following recursive expression cycle in 'xmlName': [xmlName] @

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

我已经尝试在POM.XML中搜索问题，但我没有找到任何东西。

也许问题可能出在POM.XML的某个地方：

<configuration>
                        <suiteXmlFiles>src/testResources/${xmlName}</suiteXmlFiles>
                        <argLine>-javaagent:"${settings.localRepository}/org/aspectj/aspectjweaver/${aspectj.version}/aspectjweaver-${aspectj.version}.jar"</argLine>
                    </configuration>
                    <dependencies>
                        <dependency>
                            <groupId>org.aspectj</groupId>
                            <artifactId>aspectjweaver</artifactId>
                            <version>${aspectj.version}</version>
                        </dependency>
                    </dependencies>
                </plugin>
            </plugins>
        </pluginManagement>
    </build>
    <properties>
        <xmlName>${xmlName}</xmlName>
        <maven-surefire-plugin.version>2.20.1</maven-surefire-plugin.version>

Answer 1

在属性上，必须声明一个值

<properties>
<xmlName>${xmlName}</xmlName>  <--------  <xmlName>SomeValueHere</xmlName>
</properties

您在属性中传递了一个意外的参数

Maven尝试将其传递到其他地方，可能是在构建阶段，它传递的不是一个值，而是一个参数，因此它再次在属性中查找该参数的值。然后你就有了递归消息！
