如何定义用于checkstyle的抑制定义，它们与ant和eclipse一起使用 [英] How to define suppressions-definitions for checkstyle, that work with both ant and eclipse

问题描述

我在项目checkstyle中使用，我已经在我的checkstyle中定义了一个 SuppressionFilter ，组态。我使用Apache ant通过持续集成进行自动构建。

我的问题来自于以下情况：我不想将多个文件填入基于项目的，所以checkstyle.xml和suppressions.xml都在一个名为conf（用于构建的配置）的子目录中。现在，Ant和Eclipse的工作方式不一样，用于查找suppressions.xml。

Ant在使用基于项目的基础来查找suppressions.xml后，我宣布了一个蚂蚁任务找到checkstyle.xml与checkstyle的基本配置。此checkstyle.xml现在包含以下内容：

 < module name =SuppressionFilter> 
< property name =filevalue =conf / suppressions.xml/> 
< / module> 
  

这样，ant-build会找到suppressions.xml，因为build的基础是项目-directory。

现在使用 checkstyle-plugin 为Eclipse带来了一个问题。它查找从checkstyle.xml具有（conf）的路径开始的suppressions.xml。对于Eclipse，声明必须如下所示：

 < module name =SuppressionFilter> 
< property name =filevalue =suppressions.xml/> 
< / module> 
  

编辑：即使这样不行，Eclipse似乎总是需要一个绝对的路径。 >

我想知道一种方法，Eclipse和Ant都可以使用相同的checkstyle配置。有人知道这个问题的解决方案吗？绝对路径是无法解决的，因为每个开发人员和CI-Server都有不同的路径用于项目目录。

解决方案

使用Checkstyle的属性扩展功能。在您的 checkstyle.xml中声明您的 SupressionFilter 为：

 < module name =SuppressionFilter> 
< property name =filevalue =$ {checkstyle.suppressions.file}default =suppressions.xml/> 
< / module> 
  

然后修改Ant构建脚本中的Checkstyle任务以包含嵌套属性：

 < checkstyle config =conf / checkstyle.xml> 
< fileset dir =srcincludes =** / *。java/> 
< property key =checkstyle.suppressions.filevalue =conf / suppressions.xml/> 
< / checkstyle> 
  

I use in a project checkstyle and I have defined a SuppressionFilter in my checkstyle-configuration. I use Apache ant to make automatic builds via Continuous Integration.

My problems comes from the following situation: I don't want to fill to much files into the project-basedir, so the checkstyle.xml and the suppressions.xml are both in a subdirectory named conf (for configuration for build). Now Ant and Eclipse work differently for finding the suppressions.xml.

Ant use the project-basedir as basedir for finding the suppressions.xml, after I declared an ant-task to find the checkstyle.xml with the base-configuration of checkstyle. This checkstyle.xml now contains the following:

<module name="SuppressionFilter">
    <property name="file" value="conf/suppressions.xml"/>
</module>

This way the ant-build finds the suppressions.xml, because the basedir of the build is the project-directory.

Now using the checkstyle-plugin for Eclipse brings a problem. It looks for the suppressions.xml starting with the path the checkstyle.xml has (conf). For Eclipse the declaration had to look like this, to work:

<module name="SuppressionFilter">
    <property name="file" value="suppressions.xml"/>
</module>

EDIT: Even that doesn't work, Eclipse seems to need always an absolute path.

I want to know a way, that both Eclipse and Ant can work with the same checkstyle-configuration. Someone knows a solution to this problem? Absolute paths are no solution, because every developer and the CI-Server have different paths for the project-directory.

解决方案

Use Checkstyle's property expansion functionality. In your checkstyle.xml declare your SupressionFilter as:

<module name="SuppressionFilter">
    <property name="file" value="${checkstyle.suppressions.file}" default="suppressions.xml"/>
</module>

Then modify your Checkstyle task in your Ant build script to include a nested property:

<checkstyle config="conf/checkstyle.xml">
    <fileset dir="src" includes="**/*.java"/>
    <property key="checkstyle.suppressions.file" value="conf/suppressions.xml"/>
</checkstyle>
