Checkstyle eclipse plugin: error cannot initialize Toner module of TreeWalker tree "WILDCARD_TYPE"

Question

I have a problem with the eclipse checkstyle plugin, I just installed this, and when I do the checkstyle configuration using sun_checkstyle (eclipse) in the java file, I have this error:

cannot initialize TreeWalker module - token "WILDCARD_TYPE" was not found in the list of acceptable tokens com.pupp ycrawl.tools.checkstyle.checks.whitespace.WhitespaceAroundCheck@ 2261fbd cannot initialize TreeWalker module - token "WILDCARD_TYPE" was not found in the list of acceptable tokens com.pupp ycrawl.tools.checkstyle.checks.whitespace.WhitespaceAroundCheck@ 2261fbd

But when I use the checkstyle configuration: Sun Checks or Google Checks, it works. Do you have a solution? Thanks Neyoh

Answer 1

Error in the xml file sun_checks_eclipse.xml found in your plugins folder for checkstyle (for example,. \ Eclipse \ plugins \ net.sf.eclipsecs.core_xxxxxx):

<module name="WhitespaceAround"> <property name="tokens" value="ASSIGN,BAND,BAND_ASSIGN,BOR,BOR_ASSIGN,BSR,BSR_ASSIGN,BXOR,BXOR_ASSIGN,COLON,DIV,DIV_ASSIGN,EQUAL,GE,GT,LAND,LCURLY,LE,LITERAL_ASSERT,LITERAL_CATCH,LITERAL_DO,LITERAL_ELSE,LITERAL_FINALLY,LITERAL_FOR,LITERAL_IF,LITERAL_RETURN,LITERAL_SYNCHRONIZED,LITERAL_TRY,LITERAL_WHILE,LOR,LT,MINUS,MINUS_ASSIGN,MOD,MOD_ASSIGN,NOT_EQUAL,PLUS,PLUS_ASSIGN,QUESTION,RCURLY,SL,SLIST,SL_ASSIGN,SR,SR_ASSIGN,STAR,STAR_ASSIGN,LITERAL_ASSERT,TYPE_EXTENSION_AND,WILDCARD_TYPE"/> </module> 

Just delete the last entry WILDCARD_TYPE

I suspect that people writing control style are suggesting something is wrong, for example. specific version of Eclipse.

In any case, I had it 5 minutes ago, I changed the record above, and now it works.

Answer 2

In fact, there is no WILDCARD_TYPE token for WhitespaceAroundCheck.

The list of tokens you can use is as follows:

Assignment LITERAL_IF, LITERAL_RETURN, LITERAL_SWITCH, LITERAL_SYNCHRONIZED, LITERAL_TRY, LITERAL_WHILE, LOR, LT, MINUS, MINUS_ASSIGN, MOD, MOD_ASSIGN, NOT_EQUAL, PLUS, PLUS_ASSIGN, QUESTIGN, SLESTIGN

For more information, please visit our website: http://checkstyle.sourceforge.net/config_whitespace.html

Here, follow the link, find "whitespacearound", you will find a description of how to configure verification for it. There is also information about each token if you want. just click on it.

If you have other problems, let me know.
