Maven Plugin的@Mojo和@Execute的具体使用

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 {

									}

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>

@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 {
