使用Maven启动并运行。
尝试建立一个我继承的项目。我已经解决了大部分问题，但现在看到了一个奇怪的错误：

看起来像某些与 content-package-maven-plugin 插件有关的帖子。
会喜欢人们可以提供的任何线索：）
答案 0 :(得分：13)
这件事发生在我身上：
brew upgrade
它自动将我的maven版本更新为3.3.3，似乎有一些问题，因为我收到与原始帖子完全相同的消息。
我的解决方案是：
brew uninstall maven // to get rid of 3.3.3
brew install homebrew/versions/maven32 // to install maven
brew pin homebrew/versions/maven32 // to prevent unintended upgrade
然后确保在〜/ .bash_profile上有一行指向正确的maven路径：
export M2_HOME=~/usr/local/Cellar/maven32/3.2.5 ~/.bash_profile
答案 1 :(得分：13)
对于所有AEM用户，在使用原型生成maven项目后遇到同样的问题：我通过将content-package-maven-plugin的版本更新为版本0.0.24解决了问题：
<plugin>
<groupId>com.day.jcr.vault</groupId>
<artifactId>content-package-maven-plugin</artifactId>
<version>0.0.24</version>
<extensions>true</extensions>
<configuration>
<failOnError>true</failOnError>
<username>${crx.username}</username>
<password>${crx.password}</password>
</configuration>
</plugin>
答案 2 :(得分：2)
最后，我选择了最简单的解决方案，并不需要解决自定义POM配置问题。
恢复使用Maven 3.2.5
答案 3 :(得分：1)
我正面临着类似的问题，并且回归到maven 3.0.5为我工作。
答案 4 :(得分：1)
我能够通过升级maven在我的OS X Mac上解决，例如“brew升级maven”从3.3.3升级到3.3.9，如可行的那样。
答案 5 :(得分：1)
这是Maven https://issues.apache.org/jira/browse/MNG-5787中的一个未解决的问题。我遇到了完全相同的问题，并通过将Maven从3.3.1升级到3.3.9来解决问题。
答案 6 :(得分：1)
升级POM.xml中的版本
<plugin>
<groupId>com.day.jcr.vault</groupId>
<artifactId>content-package-maven-plugin</artifactId>
<version>0.0.24</version>
<extensions>true</extensions>
<configuration>
<failOnError>true</failOnError>
<username>${crx.username}</username>
<password>${crx.password}</password>
</configuration>
</plugin>
希望，您的问题将得到解决。

我也遇到了与内容包插件相同的问题.17。我为2个客户工作，我设置了一个新项目，并使用最新的内容包插件，我认为版本.24。恢复到早期版本的3.0.5并重新启动命令提示符对我有用。
现在，我必须在版本之间切换。真是太酷了：（

我遇到了同样的问题，我使用的是MAC-OS
这个命令不起作用：
mvn -PautoInstallPackage install
然后我不得不去这个文件夹
/usr/local/apache-maven/apache-maven-3.3.3/
然后我下载3.0版本并将这些文件放入......
正在工作!!!!!!!!!!!!!
所以我把文件夹apache-maven-3.0.5但是我将名称更改为apache-maven-3.3.3，然后我关闭了终端，重新打开并放入
export PATH=$PATH:/usr/local/apache-maven/apache-maven-3.3.3/bin
现在我可以使用
mvn -PautoInstallPackage install
将我的项目上传到AEM CRX / DE

我的项目遇到了同样的问题..
避免此问题的最佳方法，即更改maven版本。此问题仅适用于3.3.3版本。因此，当我使用3.5.0版本时，我摆脱了这个问题。
