Question

Hii大家我正在尝试为Android项目生成自动化Maven构建脚本我使用Maven 3.2.5生成构建，并且在尝试为示例helloworld项目生成脚本时遇到以下问题

   Exception in thread "pool-1-thread-1"java.lang.NoClassDefFoundError:org/eclipse/aether/spi/connector/Transfer$State
at org.eclipse.aether.connector.wagon.WagonRepositoryConnector$GetTask.run(WagonRepositoryConnector.java:608)

我使用以下脚本构建

尝试在谷歌进行更改和搜索没有找到解决方案，请帮助我

Answer 1

似乎 android-maven-plugin 与 maven 版本3.2.5及更高版本之间存在兼容性问题。

对我来说，它适用于3.2.3，当我使用3.2.5和3.3.1时， NoClassDefFoundError 异常失败

尝试从档案中下载较旧的maven版本 http://archive.apache.org/dist/maven/maven-3/3.2.3/

修改

此问题已在 android-maven-plugin 的更高版本（testet with 4.1.1）中修复。插件已移至github，并重新定位到新的groupId。

  <plugin>
    <groupId>com.simpligility.maven.plugins</groupId>
    <artifactId>android-maven-plugin</artifactId>
    <version>4.1.1</version>
  </plugin>

新项目位置： https://github.com/simpligility/android-maven-plugin/

Answer 2

maven 3.2＆amp; amp; 3.3。试试这个：

# Place your local configuration in /etc/mosquitto/conf.d/
#
# A full description of the configuration file is at
# /usr/share/doc/mosquitto/examples/mosquitto.conf.example

pid_file /var/run/mosquitto.pid

persistence true
persistence_location /var/lib/mosquitto/

log_dest file /var/log/mosquitto/mosquitto.log

include_dir /etc/mosquitto/conf.d
cleansession true

线程“pool-1-thread-1”中的异常java.lang.NoClassDefFoundError：org / eclipse / aether / spi / connector / Transfer $ State
