如何打印正在使用的实际MAVEN_OPTIONS？ [英] How to print the actual MAVEN_OPTIONS that are being used?

问题描述

在构建过程中有没有办法让maven输出环境和maven变量的值？

解决方案

您可以使用 Maven帮助插件和帮助：系统目标，所以你的pom将是：

 < project xmlns =http://maven.apache.org/POM/4.0.0 xmlns：xsi =http://www.w3.org/2001/XMLSchema-instance
 xsi：schemaLocation =http://maven.apache.org/POM/4.0.0 http：// maven.apache.org/maven-v4_0_0.xsd\"> 
< modelVersion> 4.0.0< / modelVersion> 
< groupId> testMavenOpt< / groupId> 
< artifactId> testMavenOpt< / artifactId> 
< packaging> jar< / packaging> 
< version> 1.0-SNAPSHOT< / version> 
< name> testMavenOpt< / name> 
< url> http：//maven.apache.org< / url> 
<依赖关系> 
<依赖关系> 
< groupId> junit< / groupId> 
< artifactId> junit< / artifactId> 
< version> 3.8.1< / version> 
< scope> test< / scope> 
< / dependency> 
< / dependencies> 
< build> 
< plugins> 
< plugin> 
< groupId> org.apache.maven.plugins< / groupId> 
< artifactId> maven-help-plugin< / artifactId> 
< version> 2.1< / version> 
< / plugin> 
< / plugins> 
< / build> 
< / project> 
  

您应该执行 mvn help：system

Is there a way to get maven to output the value of environment and maven variables during a build? This would be very useful for debugging things when they're going wrong.

解决方案

You can use Maven Help Plugin and help:system goal, so your pom will be:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>testMavenOpt</groupId>
    <artifactId>testMavenOpt</artifactId>
    <packaging>jar</packaging>
    <version>1.0-SNAPSHOT</version>
    <name>testMavenOpt</name>
    <url>http://maven.apache.org</url>
    <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>3.8.1</version>
            <scope>test</scope>
        </dependency>
    </dependencies>
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-help-plugin</artifactId>
                <version>2.1</version>
            </plugin>
        </plugins>
    </build>
</project>

and you should execute mvn help:system
