我正在尝试使用 spring-roo 生成一个简单的 gwt 应用程序。以下是 log.roo 文件的内容:
project --projectName erp --topLevelPackage org.erp
persistence setup --provider HIBERNATE --database MYSQL
web gwt setup
项目生成后,我运行以下命令:
mvn clean package
我收到以下错误:
[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2:exec
(default) on project erp: Command execution failed. Process exited with an
error: 255 (Exit value: 255) -> [Help 1]
以下是 exec 插件配置:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.2</version>
<executions>
<execution>
<phase>process-classes</phase>
<goals>
<goal>exec</goal>
</goals>
<configuration>
<id>VerifyRequestFactoryInterfaces</id>
<executable>java</executable>
<arguments>
<argument>-cp</argument>
<classpath/>
<argument>com.google.web.bindery.requestfactory.apt.ValidationTool</argument>
<argument>${project.build.outputDirectory}</argument>
<argument>${project.groupId}.client.managed.request.ApplicationRequestFactory</argument>
</arguments>
</configuration>
</execution>
</executions>
</plugin>
错误 255 应该是什么意思?在这种情况下 exec 插件有什么用?我该如何克服这个错误?
谢谢...
