我想将java war部署到heroku ..我在我的pom.xml中提到了下面的依赖项
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.4</version>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals><goal>copy-dependencies</goal></goals>
</execution>
</executions>
</plugin>
</plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>appassembler-maven-plugin</artifactId>
<version>1.1.1</version>
<configuration>
<assembleDirectory>target</assembleDirectory>
<programs>
<program>
<mainClass>com.cim.Server.TomcatServer</mainClass>
<name>webapp</name>
</program>
</programs>
</configuration>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>assemble</goal>
</goals>
</execution>
</executions>
</plugin>
</build>
我跑了
mvn package
和我跑
D:\HUV\sri>java -cp target/classes:target/dependency/* com.cim.Server.TomcatServer
但即使我在上面的路径中有课程，我也会收到错误。我在哪里做错了？请帮忙

我也有类似的问题。
头部撞击2天后，我深入查看pom中的错误。
它与<build>部分无关。
我的问题是pom.xml中的元数据有一个额外的<packaging>war</packaging>标记。
我将元数据修改为
<modelVersion>4.0.0</modelVersion>
<groupId>com.my.apps</groupId>
<artifactId>DummyHerokuApp</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>Dummy name</name>
<description>Dummy war</description>
<url>http://maven.apache.org</url>
一切顺利。
我希望这可以帮助你们。
如果再次遇到此问题，请尝试根据heroku devcenter上提供的内容重建pom.xml，然后逐步添加依赖项或其他内容。

根据您的pom.xml文件，您使用appasssembler-maven-plugin生成运行Java应用程序的脚本。尝试使用它。 Example
类似的东西：
Compile:
mvn package appassembler:assemble
Run:
target/appassembler/bin/app.bat

我建议使用jcabi-heroku-maven-plugin，它会自动为您完成所有这些工作。您需要做的就是配置要运行的工件以及如何在那里运行它：
<plugin>
<groupId>com.jcabi</groupId>
<artifactId>jcabi-heroku-maven-plugin</artifactId>
<version>0.4.1</version>
<configuration>
<name>my-test-app</name>
<artifacts>
<artifact>com.example:example-app:jar::${project.version}</artifact>
</artifacts>
<procfile>web: java -Xmx256m -jar ./example-app.jar \${PORT}</procfile>
</configuration>
<executions>
<execution>
<goals>
<goal>deploy</goal>
</goals>
</execution>
</executions>
</plugin>
您需要在pom.xml中配置。
