powershell 中运行 -Dmaven.test.skip : Unknown lifecycle phase “.test.skip=true”

参考：cannot-run-maven-using-mvn-d-argument-within-microsoft-powershell-but-works

    When you run into problems with PowerShell's interpretation of arguments to be passed to a console EXE, try using the echoargs.exe utility that comes with the PowerShell Community Extensions. With this tool you can see how PowerShell supplies the arguments to the EXE e.g.:
    
    PS> echoargs mvn clean install -Dmaven.test.skip=true
    Arg 0 is <mvn>
    Arg 1 is <clean>
    Arg 2 is <install>
    Arg 3 is <-Dmaven>
    Arg 4 is <.test.skip=true>
    
    PS> echoargs mvn clean install '-Dmaven.test.skip=true'
    Arg 0 is <mvn>
    Arg 1 is <clean>
    Arg 2 is <install>
    Arg 3 is <-Dmaven.test.skip=true>
    Short answer - use quoting '-Dmaven.test.skip=true'

如何在plugin中使用不同的configuration

参考：Using the <executions> Tag

以 mybatis-generator 为例

<plugin>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-maven-plugin</artifactId>
    <version>${MBG.version}</version>
    <executions>
        <!-- 这是默认配置 -->
        <configuration>
            <configurationFile>${basedir}/src/main/resources/generator/generatorConfig.xml
            </configurationFile>
            <overwrite>true</overwrite>
            <verbose>true</verbose>
        </configuration>
        <execution>
            <!-- 运行方式 -->
            <!-- mvn mybatis-generator:generate@gen_old -->
            <id>gen_old</id>
            <goals>
                <goal>generate</goal>
            </goals>
            <configuration>
                <configurationFile>${basedir}/src/main/resources/generator_old/generatorConfig.xml
                </configurationFile>
                <overwrite>true</overwrite>
                <verbose>true</verbose>
            </configuration>
        </execution>
    </executions>
</plugin>

使用默认配置

mvn mybatis-generator

使用自定义配置

mvn mybatis-generator:generate@gen_old

maven 编译优化

maven-编译速度优化

导入第三方jar

可以在compile.plugin添加extdirs

<plugin>
 <groupId>org.apache.maven.plugins</groupId>
 <artifactId>maven-compiler-plugin</artifactId>
 <version>3.1</version>
 <configuration>
  <source>1.8</source>
  <target>1.8</target>
  <skip>${plugin.compile.skip}</skip>
  <compilerArguments>
   <extdirs>${project.basedir}/src/main/lib</extdirs>
  </compilerArguments>
 </configuration>
</plugin>
