如何解决 Eclipse 中 Android 应用程序的 Maven 配置问题？

Question

我在 Eclipse 中打开了类似 maven 项目的 Android 应用程序，但这里是 Maven 配置问题 - 未知？ 我读了这篇关于 springboot 项目Eclipse showing "Maven Configuration Problem: Unknown" 的帖子，但我不太了解。

整个 pom.xml 文件是：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

我使用了 Android API 21 和 Java 8。 有没有人遇到过类似的问题？

我也对这个问题感到困惑，直到我在这里找到解决方案eclipse-showing-maven-configuration-problem-unknown（与您提到的相同的 URL）

您需要在 pom.xml 属性中添加以下内容

<maven-jar-plugin.version>3.1.1</maven-jar-plugin.version>

就像下面来自我的 pom.xml 的 sn-p

<properties>
    <java.version>1.8</java.version>
    <maven-jar-plugin.version>3.1.1</maven-jar-plugin.version>
</properties>
