java - 使用 Maven 构建 Californium 失败

Question

我正在尝试构建 Californium 存储库 https://github.com/eclipse/californium使用maven。输入“mvn clean install”会产生以下输出:

[INFO] Scanning for projects...

我尝试了不同的方法，但仍然不知道如何修复此错误并继续我的工作。谁能帮我吗？

更多信息:下载并安装(mvn clean install)Californium Element Connector https://github.com/eclipse/californium.element-connector.git使 Californium 的构建更进一步，但仍然缺少一些依赖项。我认为其中之一是锎钪，但我下载后发现它也有一些构建问题......

实际上，我只想使用基于 Californium 的存储库 californium.tools ( https://github.com/eclipse/californium.tools )。我检查了californium.tools的pom.xml，它已经包含了所需的依赖项。但是，当我构建时，出现以下错误:

Answer 1

编辑: 看起来 Maven 存储库现在已在线，并且 cf-secure 中的错误已得到修复。因此只需执行第 4 步即可安装 californium 工具。

README.md 中提到的存储库似乎尚未上线。因此maven无法自动解析依赖关系。诀窍是直接从源代码以适当的顺序构建和安装 Maven Artifact 。

为了让 californium.tools 正常工作:

1. 安装 org.eclipse.californium:element-connector

   git clone https://github.com/eclipse/californium.element-connector.git
   cd californium.element-connector
   mvn clean install
   

2. 安装 org.eclipse.californium:scandium

   git clone https://github.com/eclipse/californium.scandium.git
   cd californium.scandium
   mvn clean install
   

3. 安装 org.eclipse.californium:californium-core

   git clone https://github.com/eclipse/californium.git
   cd californium
   mvn -pl :californium-core -am clean install
   

   请注意，我们仅构建 californium-core 子模块(使用 -pl :californium-core -am 标志)，因为 cf-secure 中存在导致构建失败的错误.

4. 构建 Californium 工具

   git clone https://github.com/eclipse/californium.tools.git
   cd californium.tools
   mvn -pl :cf-browser,:cf-coapbench,:cf-rd,:cf-server -am clean install
   

   我们需要排除 cf-client，因为它有一个导致构建失败的错误。

要运行任何工具，只需 cd californium.tools/run 和 java -jar ... 相应的 jar。
