提问by xtheking
I've been trying to run this Maven program all day but to no avail. I keep getting this error:
我一整天都在尝试运行这个 Maven 程序，但无济于事。我不断收到此错误：
[ERROR] Failed to execute goal org.codehous.mojo:exec-maven-plugin:1.4.0:java (default-cli) on project get-with-jersey: The parameters ‘mainClass' for goal org.codehaus.mojo:exec-maven-plugin:1.4.0:java are missing or invalid
[错误] 无法在项目 get-with-jersey 上执行目标 org.codehous.mojo:exec-maven-plugin:1.4.0:java (default-cli)：目标 org.codehaus.mojo 的参数“mainClass”： exec-maven-plugin:1.4.0:java 丢失或无效
After running mvn exec:java.
运行后mvn exec:java。
mvn clean installworks fine and builds, but running the program fails.
mvn clean install工作正常并构建，但运行程序失败。
I downloaded and placed the plugin for 1.4.0 where I believe Maven lets all it's plugins exist, but I can't figure out why it keeps crashing.
我下载并放置了 1.4.0 的插件，我相信 Maven 允许它的所有插件存在，但我不知道为什么它一直崩溃。
Here is my pom.xml.

You have not specified the main class to run:
您尚未指定要运行的主类：
mvn exec:java -Dexec.mainClass=foo.bar.MainClass
