Question

所以我努力将所有依赖项放入pom.xml文件中，但仍然无法抓住它们。

这是我的原始pom.xml

当我尝试构建项目时，它会抛出：

Error:(10, 26) java: package org.fit.layout.api does not exist

Error:(15, 28) java: package org.fit.layout.model does not exist

Error:(18, 17) java: package org.slf4j does not exist

我尝试通过以下方式添加layout-api`：

    <dependency> <groupId>cz.vutbr.fit.layout</groupId> 
<artifactId>layout-api</artifactId><version>0.0.4</version> </dependency>

但是，这仍然未被认可。

我检查了Maven仓库，但它也缺少org.fit.layout.model

https://repo.maven.apache.org/maven2/cz/vutbr/fit/layout/

我要编译和运行的项目是

https://github.com/FitLayout/tools

更新：在编译父项目时，出现以下Maven插件错误：

我添加了以下内容，但仍然无法摆脱maven插件错误：

Cannot resolve plugin org.apache.maven.plugins:maven-clean-plugin:2.5
Cannot resolve plugin org.apache.maven.plugins:maven-install-plugin:2.4
Cannot resolve plugin org.apache.maven.plugins:maven-deploy-plugin:2.7
Cannot resolve plugin org.apache.maven.plugins:maven-site-plugin:3.3

我添加了

                <artifactId>maven-compiler-plugin</artifactId>

Answer 1

您从其Github帐户中丢失了父pom。我为您找到了链接。是here。您要将其克隆到与另一个仓库相同的目录中。然后，您可以打包正在处理的项目。

编辑：从您的评论中我看到您也没有编译器插件。将其放在您的pom.xml中：

    <dependency>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>3.8.1</version>
      <type>maven-plugin</type>
    </dependency>
