Answer 1

这可能是你的问题吗？ https://bugs.eclipse.org/bugs/show_bug.cgi?id=383624

错误报告中有很多文本，但它在少数情况下提到了 "org.eclipse.jdt.internal.compiler.codegen.CodeStream.newArray" 和 Nulls。

错误标记为已修复。也许仔细检查你的版本，你可能需要更新你的 Eclipse 版本...

Answer 2

日志中的关键信息是“ArrayInitializer”。

我的解决方案是转换下面的代码

  @Builder.Default
  private String[] attrValueIdPairs = {""};

到

  @Builder.Default
  private String[] attrValueIdPairs = new String[]{""};

eclipse 错误已解决。
