将checkstyle/google_checks.xml与maven-checkstyle-plugin一起使用时出错

Question

我正在尝试将checkstyles google_checks.xml与maven-checkstyle-plugin一起使用。如果我将google_checks.xml与最新的检查式intelliJ插件一起使用，一切都是正确的，但是当我尝试通过maven-checkstyle插件配置它时，我得到了这个错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-checkstyle-plugin:2.13:check (default-cli) on project XX_XX_XX: Failed during checkstyle configuration: cannot initialize module TreeWalker - Unable to instantiate AvoidEscapedUnicodeCharacters:
Unable to instantiate AvoidEscapedUnicodeCharactersCheck 

我的pom.xml看起来像这样：

   <project xmlns="http://maven.apache.org/POM/4.0.0"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </configuration>
        </plugin>

你们对可能出错的地方有什么建议吗？

Answer 1

通过手动将checkstyle依赖项更新为latest stable version修复了此问题

<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-checkstyle-plugin</artifactId> <version>2.13</version> <dependencies> <dependency> <groupId>com.puppycrawl.tools</groupId> <artifactId>checkstyle</artifactId> <version>${checkstyle.latest.version}</version> </dependency> </dependencies> <configuration> <configLocation>${checkstyle.file.path}</configLocation> <failOnViolation>false</failOnViolation> </configuration> </plugin>

Answer 2

Maven checkstyle plugin使用checkstyle 5.7 (插件描述的第一行)。

Checkstyle 5.7没有这个检查(参见grepcode上的checks package )。

您需要禁用此检查或等待MCHECKSTYLE-261的官方修复。

我在网上做了一个演示

多模块和使用Google Chechstyle
