Checkstyle not generating reports with Maven, but showing issues while in Eclipse any hints? -

checkstyle.xml looks

<property name="severity" value="warning"/>  <property name="fileextensions" value="java, properties, xml"/>   <module name="treewalker">     <property name="tabwidth" value="4"/>     <module name="javadocmethod">         <property name="scope" value="public"/>         <property name="allowmissingparamtags" value="true"/>         <property name="allowmissingthrowstags" value="true"/>         <property name="allowmissingreturntag" value="true"/>         <property name="minlinecount" value="2"/>         <property name="allowedannotations" value="override, test"/>         <property name="allowthrowstagsforsubclasses" value="true"/>     </module>     <module name="javadocvariable">         <property name="scope" value="protected"/>     </module>     <module name="avoidstarimport"/> </module> 

pom.xml looks like

<?xml version="1.0" encoding="utf-8"?> <project xmlns="http://maven.apache.org/pom/4.0.0" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xsi:schemalocation="http://maven.apache.org/pom/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">     <modelversion>4.0.0</modelversion>     <groupid>my-group</groupid>     <artifactid>my-tests</artifactid>     <version>0.0.1-snapshot</version>     <name>my-tests</name>     <description>my-tests</description>     <properties>         <checkstyle.config.location>checkstyle.xml</checkstyle.config.location>     </properties>     <profiles>         <profile>             <id>checkstyle-profile</id>             <build>                 <plugins>                     <plugin>                         <groupid>org.apache.maven.plugins</groupid>                         <artifactid>maven-checkstyle-plugin</artifactid>                         <version>2.17</version>                         <configuration>                              <configlocation>checkstyle.xml</configlocation>                         </configuration>                         <executions>                             <execution>                                 <id>checkstyle-check</id>                                 <goals>                                     <goal>check</goal>                                 </goals>                                 <phase>test</phase>                              </execution>                         </executions>                     </plugin>                 </plugins>             </build>         </profile>      </profiles>     <dependencies>         <dependency>             <groupid>org.testng</groupid>             <artifactid>testng</artifactid>             <version>6.8.8</version>         </dependency>         <dependency>             <groupid>com.googlecode.json-simple</groupid>             <artifactid>json-simple</artifactid>             <version>1.1</version>         </dependency>         <dependency>             <groupid>com.google.code.gson</groupid>             <artifactid>gson</artifactid>             <version>2.3.1</version>         </dependency>     </dependencies>     <reporting>         <plugins>             <plugin>                 <groupid>org.apache.maven.plugins</groupid>                 <artifactid>maven-checkstyle-plugin</artifactid>                 <version>2.17</version>                 <configuration>                     <configlocation>checkstyle.xml</configlocation>                 </configuration>                 <reportsets>                     <reportset>                         <reports>                             <report>checkstyle</report>                         </reports>                     </reportset>                 </reportsets>             </plugin>         </plugins>     </reporting> </project> 

if run checkstyle in eclipse, shows me errors. on command line, checkstyle report not not generated. how can fix this?

by default maven checkstyle plugin reports violations on error level. in checkstyle.xml have declared checks report problems on warning level , that's why don't see output.

you can either declare severity of checks error in checkstyle.xml:

<property name="severity" value="warning"/> 

or change violationseverity in pom.xml:

<configuration>     <violationseverity>warning</violationseverity>     <configlocation>checkstyle.xml</configlocation> </configuration>
