如何在Maven中显示消息?
在ant中,我们确实有“echo”来显示消息,但是在maven中,我该怎么做?

您可以使用antrun插件:
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<phase>generate-resources</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<tasks>
<echo>Hello world!</echo>
</tasks>
</configuration>
</execution>
</executions>
</plugin>
但有一个问题是你必须选择the build lifecycle的哪个阶段将其绑定到(我的示例将插件绑定到generate-resources
)。与Ant不同,您不是自己控制生命周期,而只是将插件绑定到预定义生命周期中的某些点。根据您实际尝试的内容,这可能对您的用例有意义,也可能没有意义。

您可以使用Groovy Maven Plugin。
<plugin>
<groupId>org.codehaus.gmaven</groupId>
<artifactId>groovy-maven-plugin</artifactId>
<version>2.0</version>
<executions>
<execution>
<phase>validate</phase>
<goals>
<goal>execute</goal>
</goals>
<configuration>
<source>
log.info('Test message: {}', 'Hello, World!')
</source>
</configuration>
</execution>
</executions>
</plugin>
上面的配置将产生以下输出:
[INFO] Test message: Hello, World!

您可以使用Björn Ekryd中发布的Echo Maven Plugin Maven Central:
<plugin>
<groupId>com.github.ekryd.echo-maven-plugin</groupId>
<artifactId>echo-maven-plugin</artifactId>
<version>1.2.0</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>echo</goal>
</goals>
<configuration>
<message>war has changed</message>
</configuration>
</execution>
</executions>
</plugin>
[INFO] --- maven-war-plugin:2.4:war (default-war) @ mymodule ---
[INFO] Packaging webapp
[INFO] Processing war project
[INFO]
[INFO] --- echo-maven-plugin:1.2.0:echo (default) @ mymodule ---
[INFO] war has changed
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
此外,这个插件有95% code coverage,非常酷。
