Question

我在初始化阶段使用maven-properties-plugin从属性文件中读取一堆属性。

我还将jetty插件配置为将一些项目属性（包括上面读过的属性）设置为jetty的系统属性。

如果我将结果作为

运行

mvn initialize jetty:run-war

它有效。

如果我只是说

mvn jetty:run-war

失败了。如何强制在命令行上指定的目标在包含初始化阶段的生命周期中运行？

以下为我效劳。希望这可以帮助。 file：pom.xml

<profiles>
    <profile>
        <!-- mvn -Plocal -->
        <id>local</id>
        <build>
            <defaultGoal>package</defaultGoal>
            <plugins>
                <plugin>
                    <groupId>org.mortbay.jetty</groupId>
                    <artifactId>jetty-maven-plugin</artifactId>
                    <executions>
                        <execution>
                            <phase>package</phase>
                            <goals>
                                <goal>run-war</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
        </build>
    </profile>
</profiles>

如果我只说mvn jetty:run-war则失败。

这不是我所经历的。如果您查看jetty:run-war目标的文档，您会看到它：

在执行之前调用生命周期阶段package的执行。

因此，package之前的所有阶段加上package本身都会运行，因此，插件绑定到它们。事实上，通过以下POM：

<project>
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.stackoverflow</groupId>
  <artifactId>q2488581</artifactId>
  <version>1.0-SNAPSHOT</version>
  <packaging>war</packaging>
  <name>q2488581 Maven Webapp</name>
  <build>
    <plugins>
      <plugin>
        <groupId>org.mortbay.jetty</groupId>
        <artifactId>maven-jetty-plugin</artifactId>
        <version>6.1.10</version>
      </plugin>
      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>properties-maven-plugin</artifactId>
        <version>1.0-alpha-2</version>
        <executions>
          <execution>
            <phase>initialize</phase>
            <goals>
              <goal>read-project-properties</goal>
            </goals>
            <configuration>
              <files>
                <file>etc/config/dev.properties</file>
              </files>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
</project>

运行mvn jetty:run-war会产生以下输出：

$ mvn jetty:run-war

正如我们所看到的，properties:read-project-properties在initialize阶段（process-resources绑定到resources:resources之前）按预期调用。{/ p>

换句话说，我无法重现你的问题（或者你应该更具体）。

强制maven插件执行的生命周期先决条件？
