java - 错误: Could not find or load main class Mac Eclipse

Question

因此，我在运行 Mavericks 的 Mac 上使用 Eclipse，并将默认保存位置更改为另一个文件夹，但每次我尝试构建新项目时，都会不断弹出此错误...错误:无法找到或加载主课。如果这有帮助的话，这是我的两个类的代码。

//Employee.java
package Exercise314;
public class Employee 
{
String firstName;
String lastName;
double monthlySalary;

public Employee (String fName, String lName, double mSalary)
{
    firstName = fName;
    lastName = lName;
    monthlySalary = mSalary;
}
public void setFirstName (String fName)
{
    firstName = fName;
}
public void setLastName (String lName)
{
    lastName = lName;
}
public void setMonthlySalary (double mSalary)
{
    if(mSalary > -1)
        monthlySalary = mSalary;
}
public String getFirstName ()
{
    return firstName;
}
public String getLastName ()
{
    return lastName;
}
public double getMonthlySalary ()
{
    return monthlySalary;
}
}
//EmployeeTest.java
package Exercise314;
public class EmployeeTest 
{

public static void main(String[] args) 
{
    Employee employee1 = new Employee(
            "Joe", "Smith", 150000 );
    Employee employee2 = new Employee(
            "Jane", "Doe", 95000 );
    System.out.printf("First name is: %s\n",
            employee1.getFirstName() );
    System.out.printf("Last name is: %s\n",
            employee1.getLastName() );
    System.out.printf("Salary is: %f\n\n",
            employee1.getMonthlySalary() );
}
}

作为 Mac 用户并且安装了 Eclipse Luna 和 STS，我建议您重新启动 Eclipse。如果这不起作用，请重新启动 Mac。当我遇到同样的错误时，我就是这样做的。
