OpenDaylight netconf构建问题

Question

我尝试按照ODL维基的“入门”部分中的说明构建netconf模块。

我发现了可能的答案：

1. 使用正确的“setings.xml”。
2. 尝试使用不同的maven命令，如：mvn、-Pq干净安装；mvn安装-DskipTests

不幸的是，所有这些变体都不适合我。

因此，我安装了所有必要的特性，比如maven，获得了正确的‘So ings.xml’，从git中提取了netconf项目，并尝试使用mvn干净安装构建它。在那之后我犯了很多错误：

[ERROR] [ERROR] Some problems were encountered while processing the POMs:

..。

我知道问题出在“奇怪的包”里，但我不知道该怎么处理。有人有什么想法吗？

Answer 1

您的Maven存储库仍然“记得”它未能下载构建所需的OpenDaylight工件。要解决这个问题，可以强制使用-U进行更新。

mvn -U clean install

构建时还需要完整的JDK，而不是JRE，所以安装如下：

sudo apt install openjdk-8-jdk
