github 提供自定义 eclipse 插件安装

Question

我正在尝试从更新站点安装插件以用于 eclipse。但是，不知何故这不起作用（可能是工具已经结束了更新站点的支持）。虽然，我从github找到了插件的源代码（但它不是编译版本）。我可以将其下载为 zip 文件。但是，我面临与安装相关的问题。它在不同的文件夹中包含许多 plugin.xml 个文件。但是，我不确定使用哪一个。

这是插件源代码url。

请帮助完成从源代码安装 eclipse 插件的步骤。

@ChandrayyaGK：我已按照您的 answer.I 中提到的步骤进行操作，但遇到以下错误。

经过更多调查，我发现原因是由于机器环境属性。

<environment>
                        <os>macosx</os>
                        <ws>cocoa</ws>
                        <arch>x86_64</arch>
                    </environment>

我已经改成关注了，可以用了。

<environment>
                            <os>win32</os>
                            <ws>win32</ws>

                        </environment>

Answer 1

您必须拥有 github 帐户才能从 github 克隆或下载源代码。创建您的 github 帐户，然后转到此项目，然后单击 克隆或下载 按钮，然后将源下载为 zip 文件。
您必须构建这些源代码才能获得 eclipse 插件，因此请解压缩内容。
graphiti p2 存储库的位置现在已更改，因此请打开文件 /Activiti-Designer-master/org.activiti.designer.parent/pom.xml 并从
更改行
<graphiti-site>http://download.eclipse.org/graphiti/updates/0.11.4</graphiti-site> 至

<graphiti-site> http://archive.eclipse.org/graphiti/updates/0.11.4</graphiti-site>
在命令提示符中转到 Activiti-Designer-master/org.activiti.designer.parent 文件夹，然后运行命令 mvn clean install（如果未安装，请安装 maven）。
我试过了并且能够在我的机器上成功构建这个插件。默认情况下，它为 eclipse luna 平台构建插件。因此，打开 eclipse luna 并添加 /Activiti-Designer-master/org.activiti.designer.updatesite/target/repository 文件夹作为您的更新站点，然后单击安装。 Refer this 用于在 luna 中安装新的 software/plugin。

Answer 2

关于获取 graphiti p2 存储库。

唯一对我有用的解决方案是从本地文件夹中获取 graphiti 站点。就像这里描述的那样 Activiti Designer - build failures

下载 ZIP 文件：http://archive.eclipse.org/graphiti/archives/0.11.4/org.eclipse.graphiti.site_0.11.4.201507011432.zip
解压缩并相应地设置 org.activiti.designer.parent/pom.xml 值指向解压缩的文件夹

在我的例子中是 windows 目录，例如： file:///C:/temp/org.eclipse.graphiti.site_0.11.4.201507011432

之后我就可以成功构建设计器了。

ps。抱歉，伙计们，我没有足够的声誉点数来将此作为对先前答案的评论，它似乎更明显的地方。
