如何用exec-maven-plugin插件执行jar包??报错

如标题所问，使用下面配置会报错找不到文件，但目录下确实有这个jar包(目录问题排除)

 执行注释的run.bat没有问题，求帮助

<plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>exec-maven-plugin</artifactId>
                <version>1.4.0</version>
                <executions>
                    <execution>
                        <phase>generate-sources</phase>
                        <goals>
                            <goal>exec</goal>
                        </goals>
                        <configuration>
                            <executable>java -jar tlog-gen-1.0.0-jar-with-dependencies.jar</executable>
                            <!--<executable>run.bat</executable>-->
                        </configuration>
                    </execution>
                </executions>
            </plugin>
