如何让Maven参战:爆炸而不是战争:战争

Question

我有一个使用的Maven pom <packaging>war</packaging>.但实际上,我不想构建war文件,我只想要收集所有依赖的jar并创建一个完整的部署目录.

所以我正在运行war:exploded生成部署目录的目标:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <executions>
        <execution>
            <phase>package</phase>
            <configuration>
                <webappDirectory>target/${env}/deploy</webappDirectory>
                <archiveClasses>true</archiveClasses>
            </configuration>
            <goals>
                <goal>exploded</goal>
            </goals>
        </execution>
    </executions>
</plugin>

问题是,战争文件仍然建立.是否有一种简单的方法来<packaging>war</packaging>执行war:exploded目标而不是战争:战争目标？

或者还有另一种简单的方法吗？

Answer 1

解决方案非常简单.您需要覆盖war插件的默认执行以禁用它并添加您自己的执行(用于爆炸):

<pluginManagement>
    <plugins>
            <plugin><!-- don't pack the war  -->
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <executions>
                    <execution>
                        <id>default-war</id>
                        <phase>none</phase>
                    </execution>
                    <execution>
                        <id>war-exploded</id>
                        <phase>package</phase>
                        <goals>
                            <goal>exploded</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
    </plugins>
</pluginManagement>

Answer 2

根据包装阶段战争中war包装的内置生命周期绑定:war mojo被称为.

您可以调用之前的'prepare-package'阶段 - 所有操作都将执行,并在此之后调用mojo war:爆炸

mvn prepare-package war:exploded

结果将与您的相同,但不会产生战争.

Answer 3

我想升级到@Michael Wyraz的答案,只是包含安装跳过设置,以防有人mvn clean install在多模块项目的顶层执行构建,其中一个子模块是web应用程序.

这站在战争模块内:

<profiles>
    <profile>
        <id>war_explode</id>
        <build>
            <pluginManagement>
                <plugins>
                    <plugin>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-war-plugin</artifactId>
                        <version>2.6</version>
                        <executions>
                            <execution>
                                <id>default-war</id>
                                <phase>none</phase>
                            </execution>
                            <execution>
                                <id>war-exploded</id>
                                <phase>package</phase>
                                <goals>
                                    <goal>exploded</goal>
                                </goals>
                            </execution>
                        </executions>
                    </plugin>
                    <plugin>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-install-plugin</artifactId>
                        <executions>
                            <execution>
                                <id>default-install</id>
                                <phase>none</phase>
                            </execution>
                        </executions>
                    </plugin>
                </plugins>
            </pluginManagement>
        </build>
    </profile>
</profiles>

没有安装跳过构建失败,因为它尝试将war安装到.m2文件夹中.错误消息如下所示:

[INFO] --- maven-install-plugin:2.4:install (default-install) @ *** ---
[INFO]   ------------------------------------------------------------------------
[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-install-plugin:2.4:install (default-install) on project ***: The packaging for this project did not assign a file to the build artifact -> [Help 1]

执行mvn clean install -P war_explode此设置(包含在名为war_explode的 maven配置文件中),它完成构建而没有错误.

Answer 4

我能想到做你想做的事的唯一方法是设置使用pom包装(或创建自定义包装)并将所需的目标从战争包装绑定到生命周期的相关阶段.如果你去pom打包你可以使用在一个配置文件中定义war:war执行来允许你打包它,但是你需要使用build-helper-maven-plugin attach-artifact目标来将战争附加到POM.

注意这种方法如果你想使用任何其他特定于战争的处理,它可能会导致你的问题.

战争包装的生命周期绑定在"构建生命周期简介"中列出(请参阅"默认生命周期绑定 - 打包ejb/ejb3/jar/par/rar/war"部分).

要将相关的插件执行绑定到pom包装,您可以执行以下操作:

<build>
  <plugins>
    <plugin>
      <artifactId>maven-resources-plugin</artifactId>
      <executions>
        <execution>
          <id>process-resources</id>
          <phase>process-resources</phase>
          <goals>
            <goal>resources</goal>
          </goal>
        </execution>
      </executions>
    </plugin>
    <plugin>
      <artifactId>maven-compile-plugin</artifactId>
      <executions>
        <execution>
          <id>compile</id>
          <phase>compile</phase>
          <goals>
            <goal>compile</goal>
          </goal>
        </execution>
      </executions>
    </plugin>
    <plugin>
      <artifactId>maven-resources-plugin</artifactId>
      <executions>
        <execution>
          <id>process-test-resources</id>
          <phase>process-test-resources</phase>
          <goals>
            <goal>testResources</goal>
          </goal>
        </execution>
      </executions>
    </plugin>
    <plugin>
      <artifactId>maven-surefire-plugin</artifactId>
      <executions>
        <execution>
          <id>test</id>
          <phase>test</phase>
          <goals>
            <goal>test</goal>
          </goal>
        </execution>
      </executions>
    </plugin>
    <!-- package not wanted, install and deploy already defined for pom packaging-->
    <!--define war:war execution in a profile in case it is needed-->
