我是maven的新手,在通过maven运行类文件时遇到问题

运行良好 mvn exec:java -Dexec.mainClass =“com.test.Test”

但不是与 mvn exec:exec -Dexec.executable = java -Dexec.mainClass =“com.test.Test”

它要求java参数

F:\data\work\Test>mvn exec:exec -Dexec.executable=java -Dexec.mainClass="com.test.Test"
Usage: java [-options] class [args...]
           (to execute a class)
   or  java [-options] -jar jarfile [args...]
           (to execute a jar file)
where options include:
    -d32          use a 32-bit data model if available
    -d64          use a 64-bit data model if available
    -server       to select the "server" VM
    -hotspot      is a synonym for the "server" VM  [deprecated]
                  The default VM is server.

    -cp <class search path of directories and zip/jar files>
    -classpath <class search path of directories and zip/jar files>
                  A ; separated list of directories, JAR archives,
                  and ZIP archives to search for class files.

我已经提供了一个类文件然后为什么它不能选择它? 我试着通过pom提供这些。

我正在使用exec:exec,因为我不想从 MAVEN_OPTS

传递VM参数

这是我的pom

<profiles>  
 <profile>  
  <id>fib</id>  
  <build>  
   <plugins>  
    <plugin>  
     <groupId>org.codehaus.mojo</groupId>  
     <artifactId>exec-maven-plugin</artifactId>  
     <version>1.3.2</version>  
     <executions>  
      <execution>  
       <phase>test</phase>  
       <goals>  
        <goal>exec</goal>  
       </goals>  
       <configuration>  
        <mainClass>com.test.Test</mainClass>  
        <executable>java</executable> 
       </configuration>  
      </execution>  
     </executions>  
    </plugin>  
   </plugins>  
  </build>  
 </profile>  
</profiles>

我错过了什么?

所以出现2个问题 -
1)尽管传递了mainClass,但是我要求我传递java参数是什么? 2)如何使用exec-maven-plugin传递VM参数?

我发现这是第二个问题 using maven 'exec:exec' with arguments

答案 0 :(得分:4)

mvn exec:exec -Dexec.executable=java -Dexec.args="-classpath target/classes -XX:+PrintGCDetails com.test.Test"

如果您担心依赖于classpath然后make a fat jar并在classpath中设置
