从源代码构建 C3p0 时出现错误

发布于 2024-10-10 14:27:15 字数 16492 浏览 2 评论 0原文

我下载了源代码（v 0.9.1.2）并尝试构建它，首先从 命令行，然后在 IDE 中。

我认为问题是在 build.properties 文件中设置类路径。 这是我当前的类路径。当然，我尝试过各种事情 在这里，但都给出相同的结果：

j2ee.classpath=C:/glassfishv3/glassfish/lib/j2ee.jar
and tried:
j2ee.jar.base.dir=C:/glassfishv3/glassfish/lib
etc.

这是我得到的错误：

init-codegen:

I downloaded the source (v 0.9.1.2) and tried building it, first from
command line and then inside an IDE.

I think the problem is setting classpath in the build.properties file.
Here is my current classpath. Of course, I've tried various things
here, but all give the same results:

j2ee.classpath=C:/glassfishv3/glassfish/lib/j2ee.jar
and tried:
j2ee.jar.base.dir=C:/glassfishv3/glassfish/lib
etc.

Here are the errors I get:

在我看来，您正在尝试使用 Java6 进行构建，但这是行不通的。
c3p0 0.9.1.2 版本仅适用于 Java5。

您需要尝试使用 JDK1.5 再次构建它。

不幸的是，“ant clean”目标无法 100% 清理，因此您可能需要删除文件夹并重新开始。

无论如何，你为什么要尝试从源代码构建？
有一个二进制文件可供下载，看起来您只是让自己的事情变得复杂。

It looks to me like you're trying to build with Java6, and that won't work.
The 0.9.1.2 version of c3p0 only works with Java5.

You'll need to try building it again with JDK1.5

Unfortunately, the "ant clean" target doesn't clean up 100%, so you'll probably want to delete your folder and start again.

Why are you trying to build from source anyway?
There's a binary download available, and it looks like you're just complicating things for yourself.
