Config Maven 2在编译阶段打印出javac命令 [英] Config Maven 2 to print out javac commands during compile phase

问题描述

有没有办法强制Maven 2（> 2.0.10）打印它正在执行的实际javac命令。即使我们使用MAVEN_OPTS提升了最大值，我们仍然会耗尽内存。我希望能够看到正在执行的内存不足的实际命令。

Is there any way to force Maven 2 (>2.0.10) to print the actual javac commands it's executing. We keep running out of memory even though we've bumped up the max using MAVEN_OPTS. I'd like to be able to see the actual command being executed that is running out of memory.

我尝试在pom文件的插件中使用下面的详细设置管理部分，但似乎没有给我javac命令：

I've tried using the verbose setting below in the pom file's plugin management section but that doesn't seem to give me the javac command:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
        <source>1.5</source>
        <target>1.5</target>
        <maxmem>1024m</maxmem>
        <compilerArguments>
            <verbose/>
        </compilerArguments>
    </configuration>
</plugin>

推荐答案

您是否尝试使用<$ c $运行Maven c> -X 命令打印调试信息？

Have you tried running Maven with the -X command to print debugging information?

$ mvn -?
...
 -X,--debug      Produce execution debug output

然后，maven-javac-plugin应该打印出正在使用的类路径，源目录/路径等。

The maven-javac-plugin should then print out the classpath being used, the source directories/path, etc.
