如果我通过命令行在预打包项目的 SampleServices中使用mvn clean install ，所有这一切都很好。 但是当我试图通过eclipse m2e mvn clean install它时，它给了我这个错误
无法执行目标org.codehaus.mojo：项目SampleServices上的exec-maven-plugin：1.4.0：exec（包）：命令执行失败。 无法运行程序“mvn”（目录“/ Users / johndoe / Project / ChickenEngine / SampleServices / target / capp”）：error = 2，没有这样的文件或目录 - > [Help 1]
我试过使用位于/opt外部maven，但仍然没有成功。 我正在遵循本指南。
All are good if I used mvn clean install via command line inside SampleServices of the pre-packaged project. But it gives me this error when I try to mvn clean install it via eclipse m2e
Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.4.0:exec (package) on project SampleServices: Command execution failed. Cannot run program "mvn" (in directory "/Users/johndoe/Project/ChickenEngine/SampleServices/target/capp"): error=2, No such file or directory -> [Help 1]
I've tried using external maven located at /opt but still no success. I'm following this guide.

最终发现要更多关注问题
SampleServices \ pom.xml配置exec-maven-plugin。 maven本身被称为可执行文件的重要部分
<executable>mvn</executable> <workingDirectory>${project.build.directory}</workingDirectory> <arguments>....这意味着mvn.bat必须在PATH中。 配置或用户变量PATH或从cmd运行eclipse，但在执行之前
set PATH=%PATH%;c:\path-to-maven-bin-directory\只有这样
./eclipse.exe你会进入eclipse控制台

SampleServices\pom.xml configure exec-maven-plugin. Important part is maven itself is called as executable
<executable>mvn</executable> <workingDirectory>${project.build.directory}</workingDirectory> <arguments>....This means that mvn.bat has to be in PATH. Configure or user variable PATH or run eclipse from cmd, but before execute
set PATH=%PATH%;c:\path-to-maven-bin-directory\and only then
./eclipse.exeand u will get in eclipse console
