如何在Maven中为生成的源创建文件夹? [英] How to create folder for generated sources in Maven?

问题描述

我必须使用wsimport生成源，并且我假设它应该转到/target/generation-sources/wsimport而不是/src/main/java.

I have to generate sources using wsimport and i assume that it should go to /target/generated-sources/wsimport rather than /src/main/java.

问题是wsimport需要在执行之前创建目标文件夹，并且失败.我可以先使用任何Maven插件创建该目录吗?我可以使用ant来做到这一点，但我更喜欢将其保存在POM中.

The problem is that wsimport needs target folder created before execution and it fails. Can I create that dir first using any maven plugin. I can do it using ant but i prefer to keep it in POM.

这是一个正确的假设.

我从来没有注意到这个问题(并且将其视为一个错误，插件必须负责处理此类问题).

I never noticed this problem (and would consider it as a bug, a plugin has to take care of such things).

怪异的部分是 File#mkdirs() :

public void execute()
    throws MojoExecutionException
{

    // Need to build a URLClassloader since Maven removed it form the chain
    ClassLoader parent = this.getClass().getClassLoader();
    String originalSystemClasspath = this.initClassLoader( parent );

    try
    {

        sourceDestDir.mkdirs();
        getDestDir().mkdirs();
        File[] wsdls = getWSDLFiles();
        if(wsdls.length == 0 && (wsdlUrls == null || wsdlUrls.size() ==0)){
            getLog().info( "No WSDLs are found to process, Specify atleast one of the following parameters: wsdlFiles, wsdlDirectory or wsdlUrls.");
            return;
        }
        ...
     }
     ...
}

您能展示一下如何调用插件及其配置吗?

Could you show how you invoke the plugin and its configuration?
