java - struts2-archetype-blank 上的 Maven fatal error

Question

我正在尝试使用 maven 启动一个新的 struts 2 项目(struts2 空白原型(prototype))下面的代码运行并生成项目及其 pom.xml

D:\Dev\IndigoWS>mvn archetype:generate -B DgroupId=com.proj.core -DartifactId=MyStruts2Blank -DarchetypeGroupId=org.apache.struts -DarchetypeArtifactId=struts2-ar
chetype-blank -DarchetypeVersion=2.2.1

来自终端的以下堆栈跟踪。

但每当我尝试使用命令将其转换为 Eclipse 项目时

mvn eclipse:eclipse -Dwtpversion=1.5

我遇到了下面的 fatal error

D:\Dev\MyWorkspace>cd MyStruts2Blank

D:\Dev\MyWorkspace\MyStruts2Blank>mvn eclipse:eclipse -Dwtpversion=1.5

和maven版本

Apache Maven 2.2.1 (r801777; 2009-08-07 03:16:01+0800)
Java version: 1.6.0_24
Java home: C:\Program Files\Java\jdk1.6.0_24\jre
Default locale: en_US, platform encoding: Cp1252
OS name: "windows xp" version: "5.1" arch: "x86" Family: "windows"

我需要做什么来解决这个问题并成功生成一个 struts 2 空白原型(prototype)。我可以使用 maven 成功创建 struts 2 的入门原型(prototype)，但空白原型(prototype)没有成功。空白原型(prototype)不再可用了吗？顺便说一句，我正在使用Eclipse Indigo版本:Indigo，发布版本ID:20110615-0604提前谢谢大家。

Answer 1

首先，我必须说不要再将 mvn eclipse:eclipse 与 Eclipse Indigo 联系起来，因为您将 m2e 作为 Indigo 的一部分，此外还通过 Eclipse Marketplace 安装 m2e wtp 插件。你的project.version在哪里定义的，因为你使用它与你的struts版本相关，但在你的pom中你没有定义任何版本。

<?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"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <modelVersion>4.0.0</modelVersion>
    <groupId>com.royj.core</groupId>
    <artifactId>MyStruts2Blank</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <packaging>war</packaging>
    <name>Struts 2 Blank Webapp</name>

    <properties>
        <struts2.version>2.3.1.2</struts2.version>
    </properties>
...
</project>

除此之外，我建议升级到 Maven 3.0.3，因为 Eclipse Indigo 使用嵌入的 Maven 3。
