Question

为什么我无法运行此jar文件？我成功地清理并构建了项目。但是当我尝试在命令提示符下运行jar文件时，我得到的错误就像

java -jar FSP-1.3.0 rc 1.jar

Error: Unable to access jarfile FSP-1.3.0

这是在netbeans IDE 7.2.1中完成的maven项目。下面是我的pom.xml

请尽快回复我。请告诉我这里我做错了什么？

Answer 1

Java正在绊倒文件名中的空格。将您的版本从“1.3.0 rc 1”重命名为“1.3.0-rc-1”，或者在从命令行调用java时将文件名放在引号中：

java -jar“FSP-1.3.0 rc 1.jar”

Answer 2

几个选项

1）正如Joachim建议在jar文件周围加上引号

java -jar "FSP-1.3.0 rc 1.jar"

2）转义jar名称中存在的空格

java -jar FSP-1.3.0\ rc\ 1.jar

两者都应该有用。

为什么我无法运行maven项目的这个jar文件？
