JavaScript 验证器在 Eclipse 中抛出 NullPointerException

JavaScript validator throws NullPointerException in Eclipse

提问by Leahcim

I'm coding some PHP files on Eclipse IDE, and I keep getting an error that says "Building Workspace has encountered a problem" -- Workspace is the name of my project area.

我正在 Eclipse IDE 上编写一些 PHP 文件，但我不断收到一条错误消息，提示“构建工作区遇到问题”——工作区是我的项目区域的名称。

When I click on the "details" link I get this

当我点击“详细信息”链接时，我得到了这个

Errors occurred during the build.
Errors running builder 'JavaScript Validator' on project 'Ullman'.
java.lang.NullPointerException

As mentioned, I'm working in PHP so I don't know why it's trying to set up JavaScript Validator. I can't figure out how to stop it from doing these things. Anyone know?

如前所述，我正在使用 PHP，所以我不知道它为什么要尝试设置 JavaScript 验证器。我不知道如何阻止它做这些事情。有人知道吗？

I'm not experienced, so please provide a detailed answer if you can.

我没有经验，所以如果可以，请提供详细的答案。

I just ran into this problem myself and the previous accepted answer was not helpful. The problem is not the validator, it is the build. To fix go to Project -> Properties -> Builders, then disable ‘JavaScript Validator'. Since you are working with PHP your build is getting confused when you try and validate a PHP file with a JavaScript validator.

我自己刚刚遇到了这个问题，之前接受的答案没有帮助。问题不在于验证器，而在于构建。要修复，请转到Project -> Properties -> Builders，然后禁用“JavaScript Validator”。由于您正在使用 PHP，当您尝试使用 JavaScript 验证器验证 PHP 文件时，您的构建会变得混乱。

The error message doesn't really do anything it just gets annoying really fast.

错误消息并没有真正做任何事情，它只会很快变得烦人。

UPDATE: Cleanshooter's answer is the better one for PHP-specific projects. I'm leaving this answer since it is useful for people who run across the error on JavaScript files because of crashes in the JavaScript parser.

更新：对于特定于 PHP 的项目，Cleanshooter 的答案是更好的答案。我要留下这个答案，因为它对因 JavaScript 解析器崩溃而在 JavaScript 文件上遇到错误的人很有用。

You can disable part of the JavaScript validator with Eclipse -> Preferences -> JavaScript -> Validator -> Errors/Warnings and unchecking Enable JavaScript semantic validation

您可以使用 Eclipse -> Preferences -> JavaScript -> Validator -> Errors/Warnings 禁用部分 JavaScript 验证器并取消选中启用 JavaScript 语义验证

For those of you who are having trouble with 'dynamic web projects', you may find that none of the other answers work.

Just go to Project -> Build Automatically and disable this option.. you won't need it anyway with PHP.. because there is nothing to be build.. but this solves the NPE thrown at each save or f5 action

只需转到 Project -> Build Automatically 并禁用此选项.. 无论如何，PHP 都不需要它.. 因为没有什么可构建的.. 但这解决了每次保存或 f5 操作时抛出的 NPE

I ran into the same problem and the above suggestions would not resolved it completely unless until I came across to this post @ How do I remove javascript validation from my eclipse project?

我遇到了同样的问题，上面的建议不会完全解决它，除非我遇到这篇文章@如何从我的 eclipse 项目中删除 javascript 验证？

But even then after doing all (as given the other post url), had to manually removed the "Problems" tab statements like 'Errors' and 'warning' then only it goes away completely at least in Eclipse Juno.

但即使在完成所有操作之后（如给出的另一个帖子 url），也必须手动删除“问题”选项卡语句，例如“错误”和“警告”，然后至少在 Eclipse Juno 中它会完全消失。

Hope it helps someone.

希望它可以帮助某人。

This is a problem that has happened to me on some Web Dynamic projects. Every time the project is built, I get this error:

这是我在某些 Web 动态项目中遇到的问题。每次构建项目时，我都会收到此错误：

Errors occurred during the build.
Errors running builder ‘JavaScript Validator' on project ‘some-project'.
java.lang.NullPointerException

At a first sight it seems that a Javascript validatoris throwing a NullPointerException, so probably you will try to disable Client-side Javascriptvalidation from Project->Properties->Validation… but I tell you that the problem is not there, you must go to

乍一看似乎 aJavascript validator正在抛出 a NullPointerException，因此您可能会尝试禁用Client-side Javascript验证Project->Properties->Validation...但我告诉您问题不存在，您必须转到

Project->Properties->Builders

Project->Properties->Builders

then disable Javascript Validator.

然后禁用Javascript Validator。

Disabling ‘Javascript Validator' is not the ideal solution. It is just hiding the problem.

禁用“Javascript Validator”并不是理想的解决方案。它只是隐藏了问题。

What worked for me is this:

对我有用的是：

Switch to a new or a different workspace from File >Switch Workspace and then import your existing project into this new workspace.

从文件 > 切换工作区切换到新的或不同的工作区，然后将现有项目导入到这个新工作区。

Problem solved.

问题解决了。
