我有一个从 Swagger jaxrs-resteasy 生成的 Wildfly Rest 服务。该项目来自 Jetbrains IntelliJ Idea IDE，我也在运行 jrebel。整个设置一切正常，除了来自 src/gen/java 路径的所有代码（生成的代码）不断被 JRebel 删除和上传。我是否遗漏了 rebel.xml 文件中的某些内容以使其停止执行此操作？

JRebel 控制台不断循环显示以下消息，我担心电量很快就会足以为特斯拉充电......

我怀疑问题出在rebel.xml中，尽管您可以先从一个非常简单的rebel.xml开始，然后从那里继续进行验证，在您的情况下，以下应该是一个好的开始：

<?xml version="1.0" encoding="UTF-8"?>
<application generated-by="intellij" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.zeroturnaround.com" xsi:schemaLocation="http://www.zeroturnaround.com http://update.zeroturnaround.com/jrebel/rebel-2_1.xsd">
    <classpath>
        <dir name="/absolute/path/to/project/target/classes">
        </dir>
    </classpath>
</application>

最初，JRebel 进行一次同步，删除所有旧文件并上传新文件，之后 JRebel 开始监视本地构建目录 (../target/classes/) 中的所有文件更改，并在检测到时间戳更改后触发同步事件. 如果文件 md5 哈希值与之前不同，则会上传。

此外，JRebel 还可以监视可以在rebel.xml中指定的其他资源文件（Web 文件、属性文件等）。

很难说到底发生了什么，但我的猜测是，由于某种原因，生成的文件经常被重新编译（可能是自动生成的时间戳）并且 JRebel 检测到这些文件的哈希值发生了变化。您可以手动检查文件哈希并验证是否是这种情况。

如果出于某种原因，IDEA 不断重新编译和更改 .class 文件，您可以禁用 JRebel 在每次构建后自动同步。在这种情况下，您必须在需要时手动与远程服务器同步。

JRebel IntelliJ 远程服务器配置

为了弄清楚确切的原因，请将rebel.ide.log=trace添加到{user.home}/.jrebel/jrebel.properties，重新启动 IDE 并重现问题，日志将生成为jrebel-intellij.log。将其发送至support@zeroturnaround.com，他们将能够为您提供更多详细信息。
