如何在pom.xml文件中指定Java编译器版本?
我在Netbeans中编写了一些Maven代码，大约有2000多行。当我在Netbeans上编译它时，一切都很好，但如果我想在命令行上运行它，我会得到这些错误:
generics are not supported in -source 1.3
(use -source 5 or higher to enable generics)
ArrayList<ArrayList<Integer>> list = new ArrayList<ArrayList<Integer>>();
generics are not supported in -source 1.3
(use -source 5 or higher to enable generics)
HashSet<Double> resid_List = new HashSet<Double>(Arrays.asList(resid_val));
generics are not supported in -source 1.3
(use -source 5 or higher to enable generics)
List<Integer> ind_ovlpList = new ArrayList<Integer>(Arrays.asList(ind_ovlp));
generics are not supported in -source 1.3
(use -source 5 or higher to enable generics)
public class ColumnComparator implements Comparator<double[]> {
annotations are not supported in -source 1.3
(use -source 5 or higher to enable annotations)
@Override
我尝试使用Java 1.3.1，编译器错误，但我得到了更多的错误。我从其他帖子中发现我应该修改pom.xml，但我不知道如何修改。这是我的pom.xml

如果你能帮助我，那就太好了!
