Maven Plugin的@Mojo和@Execute

本文以spring-boot-maven-plugin 2.5.4为例

@Mojo defaultPhase

以spring-boot-maven-plugin:start为例, 他的@Mojo defaultPhase是PRE_INTEGRATION_TEST,该目标默认绑定到此阶段.

@Mojo(name = "start", requiresProject = true, defaultPhase = LifecyclePhase.PRE_INTEGRATION_TEST,
      requiresDependencyResolution = ResolutionScope.TEST)
public class StartMojo extends AbstractRunMojo {
}
复制代码

在pom中,我们只需要指定goal,就会在PRE_INTEGRATION_TEST阶段执行

<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<executions>
    <execution>
        <id>start</id>
        <goals>
            <goal>start</goal>
        </goals>
        <!--如果额外指定phase=verify,会忽略defaultPhase,而在verify阶段执行-->
        <phase>verify</phase>
    </execution>
</executions>
复制代码

@Execute phase

以spring-boot-maven-plugin:run为例,他的@Execute phase=TEST_COMPILE,在运行该目标前，让maven先运行一个并行的生命周期，到指定的阶段TEST_COMPLIE为止。到phase执行完，才执行插件目标
所以执行run,总是会运行到TEST_COMPLIE阶段

@Mojo(name = "run", requiresProject = true, defaultPhase = LifecyclePhase.VALIDATE,
      requiresDependencyResolution = ResolutionScope.TEST)
@Execute(phase = LifecyclePhase.TEST_COMPILE)
public class RunMojo extends AbstractRunMojo {
