问题启动弹簧roo

Question

我刚刚开始使用spring，在运行教程时，我会遇到下面的错误

roo> perform tests

我的电脑里已经安装了maven2.2.1。

命令“mvn.bat测试”未成功完成

roo>

然后我试着执行

roo> perform tests

在导入eclipse时，我遇到了以下错误：

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]

任何帮助都会很感激的。

编辑：

按照你的建议，我意识到问题在maven-eclipse-plugin-2.8.jar中。

正在运行

roo>perform月食 命令mvn.bat eclipse:clean eclipse:eclipse未成功完成

所以我决定把它运行起来，看看为什么，我面对的是：

必需的目标未找到:eclipse: org.apache.maven.plugin:maven-eclipse-plugin-2.8.jar中的eclipse

但是我去了指定的文件夹，罐子就在那里，有什么问题吗？

.m2\repository\org\apache\maven\plugins\maven-eclipse-plugin\2.8\maven-eclipse-plugin-2.8.jar

与另一个未成功完成的命令做类似的操作

mvn.bat测试

我面临另一个错误：

无法执行: mojo。它需要一个具有现有pom.xml的项目，但是构建没有使用

也许在这段中错误才是线索。roo如何创建pom.xml？

Answer 1

我也遇到了同样的问题--有两件事似乎成功了。

1. 解开拉链，重新设置Roo。如果您在Roo启动时看到“未知版本”，请执行此操作。
2. 这个似乎解决了它。检查一下你的本地美文回购。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 repo。

希望这能有所帮助。告诉我事情进展如何。

Answer 2

是啊，这也让我大惊小怪。这似乎是他们的一个简单的文档错误：

Answer 3

经过大量的搜索，我终于发现了导致这个问题的原因。这与在aspectj插件(在您的.m2回购中)中配置的工具jar的路径有关，那里也是一个类似的问题，我将提供进一步的详细信息。
