Java Runtime.getRuntime(). Exec теряет/изменяет некоторые параметры

Question

(-Dexec.mainClass=maven.MainClassmaven.MainClass становится.)

При выполнении класса Java с использованием Maven внутри Java (Eclipse plugin actualy) -Dexec.mainClass=maven.MainClassmaven.MainClass становится

package maven; 

public class MainClass { 
    public static void main(String[] args) { 
     System.out.println("app is running!"); 
    } 
} 

из Eclipse с использованием

Process p = DebugPlugin.exec(cmds, workingPath, envp); 
    RuntimeProcess process = (RuntimeProcess)DebugPlugin.newProcess(launch, p, MavenConstants.PROCESS_MESSAGE); 

что p= Runtime.getRuntime().exec(cmdLine, envp); просто вызывает Java

p= Runtime.getRuntime().exec(cmdLine, envp); 

И массив строк, которые сцепляются выглядит как строка ниже, как-то теряет -Dexec.mainClass= часть.

D:\Code\springsource\3.0\apache-maven-3.0.3\bin\mvn.bat compile exec:java -Dexec.mainClass=maven.MainClass

Answer 1

Найдено, что cmdLine.add("-Dmaven.test.skip=true"); становится просто true с подобной ошибкой.

Я не замечает никакого упоминания в JavaDoc этого поведения для Runtime.getRuntime().exec(

решена, поставив все опции в одну строку.

cmdLine.add(mavenPath); 
    cmdLine.add(mavenOptions+" compile exec:java -Dexec.mainClass="+packageClass);
