java - jOOQ:使用 maven 生成代码

Question

你好，

我正在使用 jOOQ 尝试使用 java 进行简单的 postgreSQL 设置。现在，我使用 pgadmin3 创建了一个名为 Products 的表，其中包含两列:

CREATE TABLE public."Products"
(
  id integer NOT NULL,
  username text,
  CONSTRAINT id PRIMARY KEY (id)
)
WITH (
  OIDS=FALSE
);
ALTER TABLE public."Products"
  OWNER TO postgres;

现在，我正在尝试使用 java 与此表进行交互。我可以从 postgres 请求一个表列表，所以我知道连接有效。但是，如果我尝试进行 maven 安装(以生成为目标，我想要我的 java 类)，我会收到以下错误:

类确实生成了，看起来(因为我可以在目标文件夹中找到它)。但是在 eclipse 或 intellij 中我无法在路径中找到它。 无论哪种方式，构建过程都不应失败。

有谁知道构建失败的原因？

谢谢，美好的一天。

因此，为了在 Stack Overflow 上有一个正式的答案，这里再次将我的评论作为答案。

从外观上看，您使用的是过时的 jOOQ 代码生成器版本和较新的 jOOQ 运行时版本。两者不匹配，这就是您获得这些异常(exception)的原因。

我注意到是因为 PublicFactory 类不再由 jOOQ 3.x 代码生成器生成。
