【问题描述】：

我尝试在我的 Windows 7 机器上运行 Maven（从未使用过，只是在 this 指南的帮助下安装它）来构建 Alexa Skill Kit Example

这是我的输出：

mvn -版本：

Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T17:41:47+01:00)

我该如何解决这个问题？

【问题讨论】：

你可以试试mvn clean package 命令。以及你为什么使用mvn assembly:assembly -DdescriptorId=jar-with-dependencies package 我在 git repo 的自述文件中没有看到这条指令。
顺便说一句，我尝试在我的系统上构建它并且它工作正常。
@AmitK "进入包含 pom.xml 的根目录，运行 'mvn assembly:assembly -DdescriptorId=jar-with-dependencies package'。这将生成一个名为目标目录中的“alexa-skills-kit-samples-1.0-jar-with-dependencies.jar”。“[这里]（github.com/amzn/alexa-skills-kit-java/tree/master/samples/src/…）我尝试使用mvn clean package，但问题是依赖项不会包含在 jar 中（但它已成功构建）。
它在自述文件中明确提到它需要 java 8 并且您正在尝试使用 java 7 构建它，这在您的mvn -version o/p 中明确提到。
在您提到的页面中，在 aws lambda 设置下找到了。第 6 点Select the runtime as Java 8

【解决方案1】：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.2-beta-5:assembly (default-cli) on project alexa-skills-kit: Failed to create assembly: Error creating assembly archive
jar-with-dependencies: invalid END header (bad central directory offset) -> [Help 1]

从该错误消息中可以清楚地看出，您的某些依赖项或 jar 文件已损坏。我检查了 alexa-skills-kit 并明确说明是在 AWS 中执行 maven 命令的指令，而不是从您的本地计算机？

【讨论】：

是的，我需要在本地机器上运行它。 “转到包含 pom.xml 的根目录，然后运行'mvn assembly:assembly -DdescriptorId=jar-with-dependencies package'。这将生成一个名为“alexa-skills-kit-samples-1.0-jar-”的 zip 文件with-dependencies.jar”在目标目录中。” (github.com/amzn/alexa-skills-kit-java/tree/master/samples/src/…) 稍后我会将其上传到 Amazon Lambda 服务器上。

【解决方案2】：

似乎是您的 maven-assembly-plugin 的 jar 文件已损坏。如果您首先尝试在计算机上未安装 maven 的情况下从 IDE 执行 maven build，然后才安装 maven，则可能是这样。

因此，正如之前在this 帖子中所说，您可以删除.m2/repository 目录的所有内容，然后使用maven 重建您的应用程序。
