我已经编写了上面的规则,当我尝试从命令行运行它时,我不断收到相同的消息: 无法创建Checker:无法初始化模块TreeWalker - 无法实例化LoggerAttrCheck
我已经将我的支票拆分为Checker中的一个和Treewalker中的一个,根据手册中的建议虔诚地复制了这些条目,没有任何乐趣。任何人都有自定义规则的类似问题。我是WinXP,java 1.6(Eclipse),checkstyle-5.1文件夹在路径中。 我可以提供代码,但这有点像环境问题。
代码如下:
package com.mystuff.checkstyle.hecks;
import com.puppycrawl.tools.checkstyle.api.Check;
import com.puppycrawl.tools.checkstyle.api.DetailAST;
import com.puppycrawl.tools.checkstyle.api.FullIdent;
import com.puppycrawl.tools.checkstyle.api.TokenTypes;
import com.puppycrawl.tools.checkstyle.checks.CheckUtils;
/**
*
*
* This package provides the custom checks that were required outside
* of the standard checks provided
*
*/
public class LoggerAttrCheck extends Check
{
/**
*
*
* The Logger must be declared as a static final class attribute
*
*/
@Override
public int[] getDefaultTokens()
{
return new int[] { TokenTypes.VARIABLE_DEF};
}
@Override
public void visitToken(DetailAST aAST)
{
if(aAST.getType()==TokenTypes.VARIABLE_DEF)
visitVariableDef(aAST);
}
/**
* Checks type of given variable.
* @param aAST variable to check.
*/
private void visitVariableDef(DetailAST aAST)
{
checkVariableDefn(aAST);
}
/**
*
* Checks variable to see if its a Logger and static final
* * @param aAST node to check.
*/
private void checkVariableDefn(DetailAST aAST)
{
final DetailAST type = aAST.findFirstToken(TokenTypes.TYPE);
final FullIdent ident = CheckUtils.createFullType(type);
if ((ident.getText().equals("Logger")))
{
if((!aAST.branchContains(TokenTypes.FINAL))||(!aAST.branchContainsTokenTypes.LITERAL_STATIC)))
{
log(type.getLineNo(), type.getColumnNo(),
"Logger not defined as static final class attribute", type.getText());
}
}
}
}
这构建了com.stuff.checkstyle.checks.jar,因此checkstyle_packages.xml如下所示:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE checkstyle-packages PUBLIC
"-//Puppy Crawl//DTD Package Names 1.3//EN"
"http://www.puppycrawl.com/dtds/packages_1_3.dtd">
<checkstyle-packages>
<package name="com.mystuff.checkstyle.checks"/>
</checkstyle-packages>
感谢所有的想法!
答案 0 :(得分:0)
你的checkstyle配置文件是什么样的?您的checkstyle_packages.xml
似乎被忽略了。我发现我无法将我的包添加到checkstyle-packages中,因此使用完整的包名称声明了我的检查:
<?xml version="1.0"?>
<!DOCTYPE module PUBLIC
"-//Puppy Crawl//DTD Check Configuration 1.2//EN"
"http://www.puppycrawl.com/dtds/configuration_1_2.dtd">
<module name="Checker">
<module name="TreeWalker">
<!-- Blundell specific checks -->
<module name="com.blundell.checks.AntiHungarian" />
</module>
</module>
请注意,检查的java类名称是AntiHungarianCheck,但您声明的只是AntiHungarian
取自我的自定义checkstyle示例:
