java.lang.IllegalArgumentException: windows 中格式错误的 \uxxxx 编码

Question

当我构建 Maven 项目时，它抛出以下错误。我检查了我所有的代码，没有在代码中出现 \ 或 \u 的地方。虽然很多答案和资源都指出了 / vs 中的错误，但我想提一下，我没有进行任何本地更改，而且这个 repo 对我团队中的其他人来说效果很好。它以前对我也很好用。

我已经尝试过以下方法：

在我的 mac
重新安装了 maven 试图使无效
多次尝试使缓存无效并重新启动 IntelliJ。

有人可以帮我解决这个问题吗？

Answer 1

在您的 .properties 文件中应该有一个路径属性某处。确保为此属性.

使用 / 而不是 \

如果你想使用 \ 那么你必须这样转义 \.

Answer 2

我发现我的第三方库之一在 .m2/repository 文件夹中有属性文件。

属性文件导致了问题。因此，我通过删除 .m2/repository 文件夹并使用正确的语法更新库来解决问题。

Answer 3

在代码行打断点：throw new IllegalArgumentException("Malformed \uxxxx encoding.") in Properties.java:667,

在调试模式下构建项目当调试器在断点处停止时，在堆栈中搜索有错误的输入变量的值。它将指向有问题的文件，可以是 deleted/corrected

在我的例子中是 Properties.class 中的代码：

public synchronized void load(InputStream inStream) throws IOException {
    load0(new LineReader(inStream));
}

在变量 inStream 中，我找到了一个有问题的文件名并将其删除。这解决了问题
