为了轻松运行我的webapp,我决定将Jetty添加到我的单个POM文件中。
在official documentation之后,我将其添加到我的<plugins>
:
<plugin>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>9.4.0-SNAPSHOT</version>
</plugin>
问题:mvn jetty:run
失败:
$ mvn jetty:start
[INFO] Scanning for projects...

https://mvnrepository.com/artifact/org.eclipse.jetty/jetty-maven-plugin/9.4.0.M0的另一种方法建议在<dependencies>
中添加此内容:
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>9.4.0.M0</version>
</dependency>
它也失败了,mvn jetty:start
说:

我删除了.m2
文件夹,让Maven重新创建它,没有更好的。我在settings.xml
中没有~/.m2
,这里是~/.m2/repository/org/eclipse/jetty/jetty-maven-plugin/9.4.0.M0/
的内容:
-rw-rw-r-- 1 nico nico 101524 8月 24 17:29 jetty-maven-plugin-9.4.0.M0.jar
-rw-rw-r-- 1 nico nico 40 8月 24 17:29 jetty-maven-plugin-9.4.0.M0.jar.sha1

注意:关于同一主题有几个问题,所有问题都有过时的答案,其中包含Maven ids(mortbay,codehaus),这些答案可以追溯到Jetty迁移到Eclipse之前,或者建议添加<plugin>
块。我的问题的顶部。
答案 0 :(得分:13)
您使用的是插件版本9.4.0-SNAPSHOT
。此版本在中央仓库(available versions)中不可用。
添加dependency
并不能解决问题,因为依赖项与plugin
不同。您要编译的代码使用使用依赖,而插件是编译,构建或分析您的代码。
简而言之:
dependency
jetty-maven-plugin
您必须将version
的{{1}}更改为中央或本地仓库中提供的版本。
例如:
plugin

请使用以下信息创建一个settings.xml文件
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
http://maven.apache.org/xsd/settings-1.0.0.xsd">
<localRepository>${user.home}/.m2/repository</localRepository>
<interactiveMode>true</interactiveMode>
<usePluginRegistry>false</usePluginRegistry>
<offline>false</offline>
<pluginGroups>
<pluginGroup>org.mortbay.jetty</pluginGroup>
</pluginGroups>
</settings>
这对我有用。
