Question

我是Liferay的新手，所以我开始使用官方开发者网站（https://dev.liferay.com/develop/learning-paths/mvc/-/knowledge_base/6-2/writing-your-first-liferay-application）上的教程。

当我创建我的第一个portlet时，我收到下面的Build Failed错误：

Buildfile: E:\phmathieu\liferay-plugins-sdk-6.2\portlets\build.xml

我不知道为什么我收到此消息，因为我基本上按照教程中的步骤操作。我在网上查找了类似的案例，但它还没有用。

修改

build-common-ivy.xml第81行会发生什么:(第81行是/＆gt;结束第二个 get ）

                    <if>
                    <equals arg1="@{trylocalnetwork}" arg2="true" />
                    <then>
                        <trycatch>
                            <try>
                                <get
                                    dest="${mirrors.cache.artifact.dir}"
                                    ignoreerrors="@{ignoreerrors}"
                                    src="${mirrors.src}"

                                />

                                    src="@{src}"
                                    verbose="@{verbose}"
                                />

                            ignoreerrors="@{ignoreerrors}"
                            src="@{src}"
                            verbose="@{verbose}"
                        />
                    </else>
                </if>

我使用两种方法来创建Lifery项目。走轻松的道路

下载所需内容

从此处下载Liferay IDE或Eclipse插件

https://www.liferay.com/downloads/liferay-projects/liferay-ide

下载SDK或整个插件（我更喜欢这最后一个选项）

https://github.com/liferay/liferay-plugins/releases

选择与您的Liferay匹配的那个

当您打开liferay IDE时，它会询问您的SDK。放入sdk路径（或插件文件夹）

创建项目

只需转到新的Liferay项目，然后选择项目类型。我个人总是去做maven项目。

然后你应该好好去

更复杂的方式

转到portlet文件夹的解压缩插件路径（如果你的意图是一个porlet）并调用create.sh命令

liferay-plugins-6.2.0-ga1/portlets$ ./create.sh myPortlet
Buildfile: /home/jimmy/Liferays/plugins-src/liferay-plugins-6.2.0-ga1/portlets/build.xml

create:
     [copy] Copying 9 files to /home/jimmy/Liferays/plugins-src/liferay-plugins-6.2.0-ga1/portlets/myPortlet-portlet
    [mkdir] Created dir: /home/jimmy/Liferays/plugins-src/liferay-plugins-6.2.0-ga1/portlets/myPortlet-portlet/docroot/WEB-INF/tld
     [copy] Copying 7 files to /home/jimmy/Liferays/plugins-src/liferay-plugins-6.2.0-ga1/portlets/myPortlet-portlet/docroot/WEB-INF/tld

BUILD SUCCESSFUL
Total time: 1 second

然后将其导入您喜欢的ide，因为您有许多插件，您可以将其用作自定义portlet的参考。

希望有所帮助
