How to create new directory in target folder with Maven
提问by Petr Mensik
I am writing a library which will create a report based on the test results (imagine something like Surefire). And my problem is, I am able to create a folder in target/directory to hold the report and also copy there necessary files but I can do that only when I build the library project itself.
我正在编写一个库，它将根据测试结果创建一个报告（想象像 Surefire 这样的东西）。我的问题是，我能够在target/目录中创建一个文件夹来保存报告并复制必要的文件，但只有在我构建库项目本身时才能这样做。
I would like to achieve same behavior like a Surefire plugin has, that means if I put dependency for my library to some project, let's say myProject, then I will get something like myProject/target/myLibraryafter the build.
我想实现与 Surefire 插件相同的行为，这意味着如果我将我的库依赖于某个项目myProject，那么我会myProject/target/myLibrary在构建之后得到类似的东西。
btw, this is what I currently have
顺便说一句，这就是我目前拥有的
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.7</version>
<executions>
<execution>
<phase>generate-test-sources</phase>
<configuration>
<tasks>
<echo message="Creating folder for the lib..." />
<mkdir dir="${report.folder}" />
<echo message="Copying Twitter Bootstrap libraries to the ${report.folder}" />
<copy todir="${report.folder}">
<fileset dir="src/main/resources/bootstrap">
<include name="**/**" />
</fileset>
</copy>
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
And also bonus question, is there a variable for src/main/resources?
还有奖金问题，是否有变量src/main/resources？

Ok, so I found the solution which is using the getResourceAsStream()method.
好的，所以我找到了使用该getResourceAsStream()方法的解决方案。
String classpathName = "/bootstrap/" + "css" + "/" + file;
InputStream inputStream = SetupReportDirectory.class.getResourceAsStream(classpathName);
String path = "target/myLibrary/bootstrap";
FileOutputStream outputStream = new FileOutputStream(path);
IOUtils.copy(inputStream, outputStream);

In your library, simply check if the targetdirectory (and/or whatever sub-directory you're interested in) exists. If it doesn't just use File.mkdirs(...)and create it. That's what the maven-surefire-pluginis doing.
在您的库中，只需检查target目录（和/或您感兴趣的任何子目录）是否存在。如果它不只是使用File.mkdirs(...)和创建它。这就是它maven-surefire-plugin正在做的事情。
