如何使用Netbeans在项目中显示所有Java编译器警告? [英] How to display all Java compiler warnings in a project using Netbeans?

问题描述

来自Visual Studio和Eclipse，如何找出所有编译器警告，例如整个项目未使用的变量.看起来很琐碎，但却找不到.我可以在操作项"窗口中找到所有错误，但不是所有警告.

Coming from Visual Studio and Eclipse, How to find out all the compiler warnings such as unused variables for whole project. It seems like a trivial thing but can't find it. I can find out all errors in "Action Items" window but not all warnings.

推荐答案

似乎不可能.对此有一个开放的错误报告: https://netbeans.org/bugzilla/show_bug. cgi?id = 135014 .

It doesn't seem to be possible. There is an open bug report for that: https://netbeans.org/bugzilla/show_bug.cgi?id=135014.

它是旧的，最近才分配的(请参阅错误历史记录).

It's old and just recently assigned (see bug history).

您也可以尝试使用Source→检查.它与Java编译器警告不完全相同，但有所帮助.

As an alternative you can try Source → Inspect. It's not exactly the same thing as the Java compiler warnings, but helps a bit.

例如，在下面的代码中，它捕获了未使用的导入和空变量的使用，但没有报告未使用的变量(不过，已在NetBeans编辑器中正确注释了该变量).

For example, in the code below it caught unused imports and the usage of a null variable, but didn't report the unused variable (it was correctly annotated in the NetBeans editor, though).

import java.io.InputStreamReader; // Reported unused import

public class TestJava {
    public static void main(String[] args) {

        String input = null;
        String unused; // DID NOT report unused variable

        System.out.println("Input "+ input); // Reported usage of null
    }
}

只需确保安装FindBugs插件即可充分利用它. 检查对话框将警告该插件丢失，并为您安装.

Just make sure you install the FindBugs plugin to get the most out of it. The Inspect dialog box will warn that the plugin is missing and install for you.
