找不到符号：无法识别包裹答案

【问题标题】：cannot find symbol: Package not recognized找不到符号：无法识别包裹
【发布时间】：2020-07-03 00:06:53
【问题描述】：

我无法编译这个项目，即使做了所有必要的配置，但不幸的是没有成功。

我成功编译了第一个exchange-core！使用此命令：

mvn install

这是另一个项目工作的必需依赖项。

之后，我到了目标文件夹，并启动了这个命令：

mvn install:install-file -Dfile=exchange-core-0.5.4-SNAPSHOT.jar -DgroupId=exchange.core2 -DartifactId=exchange-core -Dversion=0.0.1-SNAPSHOT -Dpackaging=jar -DgeneratePom=true

所以我可以让其他项目可以访问依赖项。

但是在尝试编译网关（将使用第一次编译的项目）时，我收到了这个错误！

这个错误：

package org.jetbrains.annotations does not exist

我认为可以通过添加 jetbrains 依赖项或从文件中删除它来解决。

但是其他的呢：

cannot find symbol
[ERROR]   symbol:   class OrderBookFastImpl
[ERROR]   location: package exchange.core2.core.orderbook

知道这个依赖来自第一个项目。

我正在使用带有图像的 docker：maven:3.5.2-jdk-8-alpine

github上的项目

我们从这行调用本地依赖：

    <dependency>
        <groupId>exchange.core2</groupId>
        <artifactId>exchange-core</artifactId>
        <version>0.5.4-SNAPSHOT</version> //<-- changed the version here to the current one
    </dependency>

【问题讨论】：

标签： java spring docker maven

【解决方案1】：

我克隆了你的 git 存储库。
您的 exchange-core 项目中没有 OrderBookFastImpl 类。

【讨论】：

好像是用旧版的，谢谢！

【解决方案2】：

看看这个：在mvn install:install-file 命令中你写了version=0.0.1-SNAPSHOT，而在pom.xml 我看到<version>0.5.4-SNAPSHOT</version>。

【讨论】：

我已经这样做了，但不幸的是再次收到同样的错误！你对这个问题有其他想法吗？谢谢！
