为什么在尝试使用 Maven 程序集插件时出现此错误消息?
Why I obtain this error message when I try to use the Maven assembly plugin?
我完全是 Maven 的新手,我正在学习教程。
在本教程中,我有以下 pom.xml 配置文件:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

正如您在这个配置文件中看到的那样,它被声明使用 assembly 插件,这部分:
<plugin>

<artifactId>maven-assembly-plugin</artifactId>
<version>2.5.5</version>
<configuration>
<descriptors>
<descriptor>jar-with-dependencies</descriptor>
</descriptors>
</configuration>
</plugin>
作为 descripor 字段,它被设置为 jar-with-dependencies 值(据我所知)必须创建一个新的目标 jar 文件,其中还包含我的项目的 delcared .jar 依赖项。
所以,在 Eclipse 中,我 select 我的项目和 运行 as ---> Maven Build 并进入 Goal 输入部分我写了这个语句:
clean package assembly:single
必须清理我的项目的目标目录,创建包并在 assembly 插件上调用 single 目标jar 依赖到我项目的最终 jar 目标文件中。
问题是这样做我在 Eclipse 控制台中收到以下错误消息:

但是根据我对教程的理解,这不是一个配置文件,而是一个特定的 Maven 值,表示将所有 .jar 依赖项放入代表我打包项目的最终目标 jar 文件中。
为什么会出现这个错误?我错过了什么?我该如何解决?
这就是我的 maven POM 在插件方面的样子。
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.16</version>
<configuration>
<testFailureIgnore>true</testFailureIgnore>

</configuration>
</plugin>

</build>
我只能假设两件事:
- 您可能没有正确格式化它,或者您使用的 maven 版本不支持您想要执行的操作。
- 您可能没有正确设置您的 bash 配置文件并规定 maven 目录所在的位置。此外,如果可能,请尝试通过 apache 网站上显示的 terminal/command 提示设置您的 Maven 项目,看看它是否有效。 Link 是:http://maven.apache.org/archetype/maven-archetype-plugin/examples/generate-batch.html
例如:这是我用来为我的一个项目创建 Maven 原型的命令:
mvn -B archetype:generate \-DarchetypeGroupId=org.apache.maven.archetypes \-DgroupId=com.weather.mobile.ios.automation.tenday \-DartifactId=IphoneTenDayAutomation
groupID 创建路径(将其视为包),而 artificatID 是 class 的名称。
您似乎没有正确使用 assembly
插件。将插件条目更改为:
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<archive>
<manifest>
<mainClass>com.test.MainClassName</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase> <!-- packaging phase -->
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
那么你只需要执行:clean install
。这将在 target
目录中创建具有依赖项的 jar。
您可以参考 link 中给出的这些示例:https://maven.apache.org/plugins/maven-assembly-plugin/examples/sharing-descriptors.html
我遇到过类似的 Maven 构建错误问题。我在更新快照选项上尝试了复选框并修复了。如果后台有旧的构建内容或缓存之类的东西,它可能会对那些人有所帮助。
