我正在嘗試創建將啟動我的 Java 應用程式的 .bat 腳本。應用程式使用了很多依賴項，所以我必須創建一個胖 jar：
我通過將此依賴項添加到我的 pom.xml 來做到這一點：
pom.xml
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>3.1.1</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>my.path.MicroserviceApp</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
之后，我執行了 maven clean install，它在我的目標檔案夾中創建了兩個 jar 檔案。一個“普通”罐子和一個胖罐子。我使用了那個胖罐子的路徑，我試圖通過我的腳本運行它，但出現錯誤。
蝙蝠腳本：
echo off
set "JAVA_HOME=C:/Program Files/Java/jdk1.8.0_291"
set "PATH=C:/Program Files/Java/jdk1.8.0_291/bin;%PATH%"
set "MICRO_HTTP=C:/Users/just.quest/workspace/application_parent/MicroserviceApp"
set "CLASSPATH=%MICRO_HTTP%/target/MicroserviceApp-20.14.1-1-jar-with-dependencies.jar"
java -jar %CLASSPATH%
pause
我得到的錯誤：

如您所見，“java.lang.IllegalArgumentException: No auto configuration classes found in META-INF/spring.factories”似乎存在一些問題。
我試過用谷歌搜索這個，但我找不到任何有用的東西，而且我已經在這上面花了太多時間，所以我別無選擇。我希望有人知道如何從命令提示符啟動應用程式。
當我從 Eclipse 啟動應用程式時，一切正常。僅當我使用 .bat 腳本時才會出現此錯誤。
uj5u.com熱心網友回復：
謝謝M. Deinum，解決了我的問題：
我不得不用以下內容替換maven-assembly-plugin：
<build>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
<configuration>
<classifier>exec</classifier>
</configuration>
</execution>
</executions>
</plugin>
</build>
