问题描述

我正在尝试使用 maven 构建 Spring-Boot *.war，但我不断收到:

I'm trying to build a Spring-Boot *.war with maven, but I keep getting:

[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 0.600 s
[INFO] Finished at: 2015-01-28T10:46:11-03:00

[INFO] ------------------------------------------------------------------------
[WARNING] The requested profile "pom.xml" could not be activated because it does not exist.

运行 mvn 后:干净.

After running the mvn: clean.

我不知道为什么，我正在关注本指南.

I have no idea why, I'm following this guide.

成功后maven在项目中生成一个target文件夹，里面只包含Manifest.mf、pom.properties和pom.xml.

After the success, maven generates a target folder in the project, it's containing only the Manifest.mf, pom.properties and pom.xml.

我是使用 maven/spring 的初学者，我没有找到任何关于它可能是什么的线索.任何帮助将不胜感激.

I'm a beginner using maven/spring and I haven't find any clues about what it might be. Any help would be appreciated.

警告信息

[WARNING] The requested profile "pom.xml" could not be activated because it does not exist.

意味着您以某种方式将 -P pom.xml 传递给 Maven，这意味着有一个名为 pom.xml 的配置文件；找到它并激活它".检查您的环境和您的 settings.xml 是否有此标志，并查看各种 XML 文件中的所有 元素.

means that you somehow passed -P pom.xml to Maven which means "there is a profile called pom.xml; find it and activate it". Check your environment and your settings.xml for this flag and also look at all <profile> elements inside the various XML files.

通常，mvn help:effective-pom 也有助于查看真正的 POM 是什么样子.

Usually, mvn help:effective-pom is also useful to see what the real POM would look like.

现在错误意味着您尝试配置 Maven 以构建 Java 8 代码，但您没有使用 Java 8 运行时.解决方案:

Now the error means that you tried to configure Maven to build Java 8 code but you're not using a Java 8 runtime. Solutions:

  1. 安装 Java 8
  2. 如果您安装了 Java 8，请确保 Maven 使用它.JAVA_HOME 是你的朋友
  3. 将 pom.xml 中的 Java 编译器配置为您实际拥有的 Java 版本.
  1. Install Java 8
  2. Make sure Maven uses Java 8 if you have it installed. JAVA_HOME is your friend
  3. Configure the Java compiler in your pom.xml to a Java version which you actually have.
