Question

当我尝试构建maven时，我的项目中出现以下错误。我正在使用eclipse，maven和liferay：

[INFO] Scanning for projects...
[ERROR] [ERROR] Some problems were encountered while processing the POMs:
[ERROR] 'dependencies.dependency.version' for com.liferay.portal:portal-service:jar must be a valid version but is '${liferay.version}'. @ line 98, column 13
[ERROR] 'build.plugins.plugin.version' for com.liferay.maven.plugins:liferay-maven-plugin must be a valid version but is '${liferay.maven.plugin.version}'. @ line 16, column 14

用maven在eclipse中构建我的项目。我写错了liferay版本吗？这是POM，请帮帮我！

如何避免上述错误？

Answer 1

如果要将版本作为属性传递，则必须定义它们：

<properties>
    <liferay.version>your_liferay_version</liferay.version>
    <liferay.maven.plugin.version>your_maven_plugin_version</liferay.maven.plugin.version>
</properties>

Answer 2

您在配置文件中配置了版本。

如果您不需要配置文件，请不要使用任何配置文件，并在全局（为您的pom）配置资源

<project><properties><liferay.version>....</liferay.version>

如果您想使用个人资料，可以阅读： http://maven.apache.org/guides/introduction/introduction-to-profiles.html

我的pom.xml使用liferay和maven有什么问题（无法读取dependencies.dependency.version）
