maven - Liferay 的父 Pom 构建问题

Question

我正在尝试设置一个基于 maven 的小型项目结构，如下所示

Maven结构

Project
\pom.xml
\Hello world portlet
  \pom.xml
\Second Portlet
  \pom.xml

如您所见，Project 下有几个 portlet(在 future 的主题中，hook 等在相同的结构下)。

现在，在单个 portlet 中，我可以运行 liferay 相关的 maven 任务，通过点击 来单独部署它们。 mvn clean 编译包 liferay:deploy
现在我正在寻找使用相同的命令构建和部署所有与 Liferay portlet 相关的 Artifact 。在这种情况下，我收到父项目本身的错误(子 Liferay 模块正在构建良好)。我不确定为什么它也尝试构建父项目，尽管我的意图只是运行 liferay:deploy 相关任务。

子 POM

这是child的pom.xml(这是创建portlet时默认生成的)

父 POM

这是父级的 pom.xml。 (我为此手动创建了谷歌搜索并将模块添加到其中)

<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">

  <groupId>com.test</groupId>
  <artifactId>MvnProject</artifactId>
  <version>1.0</version>
  <packaging>pom</packaging>

     <!-- 3. List all children projects names (name is directory name as well). -->
  <modules>
    <module>ipc-portlet</module>
    <module>helloworld</module>
  </modules>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

  <dependencies>
    <dependency>

      <artifactId>junit</artifactId>

如您所见，对于我想要的子模块，构建是成功的。但它也试图为 parent 执行它。我怎样才能避免发生第三次构建，这是父项目。

Answer 1

您必须添加自定义 pluginGroup到settings.xml像这样:

<pluginGroups>
  <pluginGroup>com.liferay.maven.plugins</pluginGroup>
</pluginGroups>

然后，您可以使用 3rd 方插件进行短调用，例如 liferay:deploy .看 this更多细节。
