Question

当我尝试为WAR项目运行命令mvn archetype:create-from-project时，在读取.java文件后会显示此异常：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:2.2:create-from-project (default-cli) on project ConfiguradorWAR: charsetName -> [Help 1]
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:2.2:create-from-project (default-cli) on project ConfiguradorWAR: charset

默认项目编码是 Cp1252 ，我已经尝试 UTF-8 和 ISO-8859-1 ，还编辑了编码选项项目和eclipse偏好。在pom.xml上：

<properties>
        <project.build.sourceEncoding>ISO-8859-1</project.build.sourceEncoding> 
        <project.reporting.outputEncoding>${project.build.sourceEncoding}</project.reporting.outputEncoding>
        <project.resources.sourceEncoding>${project.build.sourceEncoding}</project.resources.sourceEncoding>
</properties>

和

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-archetype-plugin</artifactId>
    <version>2.2</version>
    <configuration>
        <defaultEncoding>${project.build.sourceEncoding}</defaultEncoding>
        <encoding>${project.build.sourceEncoding}</encoding>
        <archetypeArtifactId>archetype-wsjpa</archetypeArtifactId>
                        <archetypeGroupId>br.com.example</archetypeGroupId>
                        <archetypeVersion>1.0</archetypeVersion>                              <archetypeFilteredExtentions>java,xml</archetypeFilteredExtentions>
    </configuration>
 </plugin>
 <plugin>
     <artifactId>maven-compiler-plugin</artifactId>
     <version>3.1</version>
     <configuration>
         <encoding>${project.build.sourceEncoding}</encoding>
     </configuration>
 </plugin>

我从同事那里得到的最好建议是尝试用整个项目中的重音替换所有角色。我有一个带有Cp1252编码的EJB项目，默认情况下第一次尝试。提前谢谢你，抱歉我的英语不好。

Answer 1

在详尽地执行命令行的所有参数后，我发现了正确的参数。

你应该像这样创建你的原型：

mvn archetype:create-from-project -Darchetype.encoding=ISO-8859-1

正如您在Maven Archetype Plugin Docs上看到的那样，您应该使用＆＃34;用户属性archetype.encoding＆＃34;。

任何其他参数名称都将失败。

它对我有用！

Answer 2

    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>${project.build.sourceEncoding}</project.reporting.outputEncoding>
    <project.resources.sourceEncoding>${project.build.sourceEncoding}</project.resources.sourceEncoding>

我需要添加以上内容。在运行mvn archetype：create-from-project

之前，我还运行了mvn clean

由Maven Archetype上的charsetName引起的MojoFailureException
