Question

我正在尝试将checkstyles google_checks.xml与maven-checkstyle-plugin一起使用。如果我使用带有最新checkstyle intelliJ插件的google_checks.xml，一切都是正确的，但是当我尝试通过maven-checkstyle插件进行配置时，我收到此错误：

[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>
    </plugins>
</reporting>

你们有什么可能出错的建议吗？

Answer 1

通过手动将checkstyle-dependency更新为latest stable version：

来解决此问题

        <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没有此检查（请参阅grepcode上的checks package）。

您需要禁用此检查或等待MCHECKSTYLE-261的正式修复。
