Spring Roo 2.0.0.RC1 不知道自己的版本号

Question

当我启动roo.sh时，该命令记录了很多关于库版本和Roo版本的错误：

$ /opt/apps/ggg/spring-roo-2.0.0.RC1/bin/roo.sh
Auto-deploy install: org.osgi.framework.BundleException: Bundle symbolic name and version are not unique: com.github.antlrjavaparser.antlr-java-parser:1.0.15

如果我创建一个项目，则创建的 pom.xml 文件中的 Spring Roo 版本是 UNKNOWN VERSION：

  <properties>
    <roo.version>UNKNOWN VERSION</roo.version>

然后，如果我修复设置2.0.0 RC1 版本的文件，当我再次启动 Roo 控制台时，它会显示：

如何解决这个版本的问题？有可以设置版本号的文件吗？

Answer 1

我看到您正在以下文件夹中执行 roo.sh 脚本：

/opt/apps/ggg

您在该文件夹中有管理员权限吗？你能尝试在~/apps/ggg文件夹中执行roo.sh脚本吗？

如果这对你有帮助，请告诉我。

问候

Answer 2

我发现了问题：Spring Roo 使用其中包含的文件夹的名称来知道它自己的版本。将文件夹 /opt/apps/ggg/roo 重命名为 /opt/apps/ggg/spring-roo-2.0.0.RC1 后按预期工作。

我知道从http://projects.spring.io/spring-roo/下载的分发文件中原来的名字是spring-roo-2.0.0.RC1（我解压压缩成/opt/apps/ggg的时候改名了），但没想到Spring是用文件夹名知道的版本，老实说，我从来没有见过这样的行为，但是重命名文件夹名称可以解决问题。

感谢您的帮助。
