在 mvn clean package 期间仅构建 WAR 一次

Question

我有一个应该构建 war 文件的 Maven 项目。当我运行 mvn clean package 时，我在日志中看到一开始它是默认的-war:

--- maven-war-plugin:2.3:war (default-war) @ my-artifact---
 Packaging webapp

然后它使war：

--- maven-war-plugin:2.3:war (war) @ my-artifact---
 Packaging webapp

我的 pom.xml 看起来像：

<?xml version="1.0" encoding="UTF-8"?>
<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">

                            <addDefaultImplementationEntries>true</addDefaultImplementationEntries>
                            <addClasspath>true</addClasspath>
                        </manifest>
                        <manifestEntries>
                            <Implementation-Build>${project.artifactId}-${project.version}</Implementation-Build>
                            <Build-Time>${timestamp}</Build-Time>

                            <Implementation-CommittedDate>${myapp.committedDate}</Implementation-CommittedDate>
                        </manifestEntries>
                    </archive>
                    <webXml>src/main/webapp/WEB-INF/web.xml</webXml>
                </configuration>
                <executions>
                    <execution>
                        <id>war</id>
                        <phase>package</phase>
                        <goals>
                            <goal>war</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
</project>

所以我想要的是禁用默认构建-war。

您应该从 maven-war-plugin 配置中删除 <executions> 标签。默认情况下，此插件将在打包阶段执行，无需任何配置。这将是正确的配置：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.3</version>
    <configuration>
        <archive>
            <manifest>
                <addDefaultImplementationEntries>true</addDefaultImplementationEntries>
                <addClasspath>true</addClasspath>
            </manifest>
            <manifestEntries>
                <Implementation-Build>${project.artifactId}-${project.version}</Implementation-Build>
                <Build-Time>${timestamp}</Build-Time>
                <Implementation-Revision>${myapp.revision}</Implementation-Revision>
                <Implementation-CommittedRevision>${myapp.committedRevision}</Implementation-CommittedRevision>
                <Implementation-CommittedDate>${myapp.committedDate}</Implementation-CommittedDate>
            </manifestEntries>
        </archive>
        <webXml>src/main/webapp/WEB-INF/web.xml</webXml>
    </configuration>
</plugin>

在 mvn clean package 期间仅构建 WAR 一次

Build WAR only once during mvn clean package
