问题描述

我正在尝试使用以下配置将我的Maven项目配置为使用google java check样式：

I'm trying to configure my Maven project to use google java check style with the following configuration:

google_checks.xml： https://github.com/checkstyle/checkstyle/blob/master/src/main/resources /google_checks.xml

google_checks.xml: https://github.com/checkstyle/checkstyle/blob/master/src/main/resources/google_checks.xml

似乎运行 mvn checkstyle：check 一开始很好。但经过几次运行后，我开始收到以下错误：

It seems to run mvn checkstyle:check fine at first. But after a few runs I start getting the following error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-checkstyle-plugin:2.17:check 
(default-cli) on project PROJECT: Failed during checkstyle configuration: cannot initialize 
module TreeWalker - Token "METHOD_REF" was not found in Acceptable tokens list in check 
com.puppycrawl.tools.checkstyle.checks.whitespace.SeparatorWrapCheck -> [Help 1]

这是什么意思？为什么它只发生一些时间，如何摆脱它？

What does that mean? Why does it only happen some times and how do I get rid of it?

推荐答案

Token在检查
com.puppycrawl.tools.checkstyle.checks.whitespace.SeparatorWrapCheck

Token "METHOD_REF" was not found in Acceptable tokens list in check com.puppycrawl.tools.checkstyle.checks.whitespace.SeparatorWrapCheck

您正在尝试使用旧版Checkstyle的较新配置。

You are trying to use a newer configuration with an old version of Checkstyle.

https://github.com/checkstyle/checkstyle/blob/master/src/main/resources/google_checks.xml 在主中，这取决于checkstyle的快照版本。

The configuration at https://github.com/checkstyle/checkstyle/blob/master/src/main/resources/google_checks.xml is in master which is dependent on the snapshot version of checkstyle.

如果您使用谷歌配置而不做任何修改，你需要使用checkstyle中嵌入的那个。请参阅 https://stackoverflow.com/a/35486365/1016482

If you are using google configuration without any modifications, you need to use the one that comes embedded in checkstyle. See https://stackoverflow.com/a/35486365/1016482

否则，您可以集成更新版本的checkstyle以使用maven。请参阅 https://stackoverflow.com/a/27359107/1016482

Otherwise you can integrate a newer version of checkstyle to work with maven. See https://stackoverflow.com/a/27359107/1016482
