【问题描述】：

我在这个父 pom.xml 上运行 maven release:prepare 时遇到这个错误。这是一个多模块的 Maven 项目。我尝试了很多东西，但我仍然无法解决这个问题，好像某处有什么奇怪的东西。我运行相同的版本：prepare on other project，没有问题。

你知道我应该看哪里吗？

谢谢

【问题讨论】：

请出示您的 pom 文件...
我更新了 pom 但不是完整的 pom（删除了一些依赖项、属性）

标签： java xml maven pom.xml

【解决方案1】：

问题是多个模块之一有这个 https 而不是 http 但日志没有提到原因模块

    <project
        xsi:schemaLocation="https://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"
        xmlns="https://maven.apache.org/POM/4.0.0"
