maven编译包含groovy文件的项目出现编码问题

1.在idea16中使用mavn编译一个包含groovy的项目，中文字符出错。在已经百度之后添加了几个字符集

编译时的字符

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>2.3.2</version>
                <configuration>
                    <source>1.6</source>
                    <target>1.6</target>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>

maven 默认编码相关

<properties>
      <!-- 文件拷贝时的编码 -->
      <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
      <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
      <!-- 编译时的编码 -->
      <maven.compiler.encoding>UTF-8</maven.compiler.encoding>
  </properties>

groovy插件编码

<plugin>
                <groupId>org.codehaus.gmaven</groupId>
                <artifactId>gmaven-plugin</artifactId>
                <version>1.5</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>generateStubs</goal>
                            <goal>compile</goal>
                            <goal>generateTestStubs</goal>
                            <goal>testCompile</goal>
                        </goals>
                        <configuration>
                            <providerSelection>2.0</providerSelection>
                            <sources>
                                <fileset>
                                    <directory>${pom.basedir}/src/main/java/com/k/bmpt</directory>
                                    <includes>
                                        <include>**/*.groovy</include>
                                    </includes>

                                </fileset>
                            </sources>
                            <sourceEncoding>UTF-8</sourceEncoding>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

2.请问还有什么编码没有考虑到吗
