我正在尝试使用Maven构建Spring-Boot * .war,但我不断得到:
[INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS [INFO] ------------------------------------------------------------------------ [INFO] Total time: 0.600 s [INFO] Finished at: 2015-01-28T10:46:11-03:00 [INFO] Final Memory: 6M/123M [INFO] ------------------------------------------------------------------------ [WARNING] The requested profile "pom.xml" could not be activated because it does not exist.
运行mvn之后:clean。
我不知道为什么要遵循此指南。
我的pom.xml

成功之后,maven将在项目中生成一个目标文件夹,其中仅包含Manifest.mf,pom.properties和pom.xml。
我是使用Maven / spring的初学者,但至今没有找到任何线索。任何帮助,将不胜感激。

警告信息
[WARNING] The requested profile "pom.xml" could not be activated because it does not exist.
意味着你以某种方式传递-P pom.xml给了Maven,这意味着“有一个名为的配置文件pom.xml;找到并激活它”。检查你的环境以及settings.xml该标志是否存在,并查看<profile>各种XML文件中的所有元素。
-P pom.xml
Maven
pom.xml
settings.xml
<profile>
通常,mvn help:effective-pom查看实际POM的外观也很有用。
mvn help:effective-pom
现在,该错误意味着你已尝试将Maven配置为构建Java 8代码,但未使用Java 8运行时。解决方案:
JAVA_HOM
每当我做“行家清洁”时,我都会收到同样的警告。我找到了解决方案:
步骤-1右键单击Eclipse中的项目
步骤-2单击属性
步骤-3在左侧列表中选择Maven。
步骤-4您将在右侧的“活动Maven配置文件”文本框中看到“ pom.xml”。清除它,然后单击“应用”。
