未创建 MAVEN 项目

Question

我正在尝试使用 Netbeans 8.2 使用 Maven 创建一个 Web 服务，但是没有创建任何内容，并且得到以下输出。

cd D:\Applications\mavenproject1; "JAVA_HOME=C:\\Program Files\\Java\\jdk1.8.0_121\\jre" "M2_HOME=C:\\Program Files (x86)\\apache-maven-3.3.9" cmd /c "\"\"C:\\Program Files (x86)\\apache-maven-3.3.9\\bin\\mvn.cmd\" -DarchetypeGroupId=org.codehaus.mojo.archetypes -DarchetypeArtifactId=ejb-javaee7 -DarchetypeVersion=1.1 -DarchetypeRepository=http://repo.maven.apache.org/maven2 -DgroupId=com.iirosa -DartifactId=mavenproject1-ejb -Dversion=1.0-SNAPSHOT -Dbasedir=D:\\Applications\\mavenproject1 -Darchetype.interactive=false -Dmaven.ext.class.path=\"C:\\Program Files\\NetBeans 8.2\\java\\maven-nblib\\netbeans-eventspy.jar\" --batch-mode archetype:generate\""

我查看了之前与我相关的问题，并尝试了所有建议的解决方案，但没有任何效果。环境变量都设置好了：

JAVA_HOME=C:\Program Files\Java\jdk1.8.0_121
M2_HOME=C:\Program Files (x86)\apache-maven-3.3.9
MAVEN_HOME=C:\Program Files (x86)\apache-maven-3.3.9
MAVEN_OPTS=-Xms256m -Xmx512m
PATH=....;%M2_HOME%\bin;%M2%

请注意，根本没有创建项目，所以不是我无法打开项目的情况。

我已经访问了输出显示的站点，但我没有运气（：

感谢您的帮助。

Answer 1

事实上，您的 maven 插件尝试连接到 https 远程存储库 https://repo.maven.apache.org/maven2，但由于安全认证无效而失败。在你的 pom.xml 中添加以下内容

<pluginRepositories>
    <pluginRepository>
      <id>central</id>
      <name>Maven Plugin Repository</name>
      <url>http://repo1.maven.org/maven2</url>
      <layout>default</layout>
      <snapshots>
        <enabled>false</enabled>
      </snapshots>
      <releases>
        <updatePolicy>never</updatePolicy>
      </releases>
    </pluginRepository>
  </pluginRepositories>

Answer 2

这看起来您可能在使用公司代理。

您需要按照Maven - Guide to using proxies 的说明进行操作。

此外，我建议删除 M2_HOME 和 MAVEN_HOME 环境变量。见MAVEN_HOME, MVN_HOME or M2_HOME。直接设置%PATH%即可。

Answer 3

原因：我在公司的防火墙后面，导致不允许 Netbeans 下载所需的插件。

我的简单解决方案是连接到不同的网络并运行项目，它会自动开始下载所需的插件。我根本不需要更改任何文件或配置。
