Question

我刚刚开始使用Spring Roo，并遵循tutorial 我在运行

时遇到以下错误

roo> perform tests

我已经在我的电脑上安装了maven2.2.1。

命令'mvn.bat test'未成功完成

roo>

然后我尝试执行

roo> perform tests

导入eclipse时，我遇到了这个错误：

Failed to execute goal org.codehaus.mojo:aspectj-maven-plugin:1.0:compile (default) on project foo: Execution default of goal org.codehaus.mojo:aspectj-maven-plugin:1.0:compile failed: Plugin org.codehaus.mojo:aspectj-maven-plugin:1.0 or one of its dependencies could not be resolved: Could not find artifact com.sun:tools:jar:1.4.2 at specified path C:\Program Files\Java\jre6/../lib/tools.jar -> [Help 1]

任何帮助都会感激不尽。

修改
根据你的建议，我意识到问题出现在maven-eclipse-plugin-2.8.jar

中

正在运行

roo＆gt;执行eclipse
命令mvn.bat eclipse:clean eclipse:eclipse未成功完成

所以我决定运行它appart，检查原因，我面对：

未找到所需目标：eclipse：org.apache.maven.plugin中的eclipse：maven-eclipse-plugin-2.8.jar

但是我去了指定的文件夹，而jar就在那里，可能是什么问题？

的.m2 \库\组织\阿帕奇\行家\插件\行家-Eclipse的插件\ 2.8 \行家-Eclipse的插件-2.8.jar

使用另一个没有成功完成的命令做类似的事情

mvn.bat测试

我面对另一个错误：

无法执行：mojo。它需要一个带有现有pom.xml的项目，但构建不使用一个

也许在这个secon错误中是线索。如何创建一个pom.xml ???

Answer 1

我遇到了同样的问题 - 尝试了两件似乎让它起作用的事情。

解压缩并再次设置Roo。如果您在Roo启动时看到“未知版本”，请执行此操作。
这个似乎解决了这个问题。检查您当地的maven回购。导航到应下载codehaus jar的位置。删除lastUpdated文件并清除该文件夹。更新Maven依赖项或再次运行Roo命令。确保您能够连接到远程maven仓库。

希望有所帮助。让我知道它是怎么回事。

Answer 2

是的，这也让我大惊小怪。它们似乎是一个简单的文档错误：

Answer 3

经过大量的搜索，最后我发现问题导致了这个问题。它与aspectj插件中配置的工具jar的路径有关（在.m2 repo中） There是一个类似的问题，我提供了更多详细信息。

Answer 4

我有一段时间经历过这些类型的问题。我有我的JAVA_HOME和路径指向较旧的JDK，这导致我的问题。

问题开始春天roo
