我无法编辑这个项目，甚至做所有必要的倾诉，但不幸的是，没有成功。

我成功地编译了第一个交换核心！使用此命令：

代码语言：javascript
复制
mvn install

这是另一个项目工作所需的依赖项。

之后，我找到了目标文件夹，并启动了以下命令：

代码语言：javascript
复制
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

这样，我就可以让其他项目可以访问依赖项。

但是当试图编译网关(将使用第一次编译的项目)时，我会得到这个错误！

此错误：

代码语言：javascript
复制
package org.jetbrains.annotations does not exist

可以通过添加我认为的jetbrains依赖项来解决，或者从文件中删除它。

但其他人呢？

代码语言：javascript
复制
cannot find symbol
[ERROR]   symbol:   class OrderBookFastImpl
[ERROR]   location: package exchange.core2.core.orderbook

知道此依赖项来自第一个项目。

我使用的是带图像的码头：maven:3.5.2-jdk-8-alpine

关于github的项目

项目1(交换核心)：https://github.com/mzheravin/exchange-core

项目2(交换网关)：https://github.com/exchange-core/exchange-gateway-rest

我克隆了你的git存储库。

在您的OrderBookFastImpl项目中没有exchange-core类。

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