[英]Maven shade-plugin not copying classes to .jar file
我已經下載了Gatling Maven Example並嘗試在其中添加mvn shade插件,如下所示,創建了jar,但是它不包含任何類,因此在執行期間失敗
E:\projects\gatling-maven>java -jar target\gatling-maven-plugin-demo-2.2.3.jar
Error: Could not find or load main class Engine
這是我添加的pom.xml

和包裝結構是
您必須將所有資源和scala文件移動到src\\main\\resources
和src\\main\\scala
。 Shade插件將不包括您的測試資源和scala文件。 我也嘗試了shadedTestjar ,它也不起作用。 另一個選擇是您可以使用
我試過在src/main
移動您的資源和scala文件,它已經起作用了。 以下是工作Pom內容,

希望它能解決您的問題。
更改以下插件配置后嘗試,
<plugin>
<groupId>net.alchim31.maven</groupId>
<artifactId>scala-maven-plugin</artifactId>
<version>${scala-maven-plugin.version}</version>
<executions>
<execution>
<goals>
<goal>compile</goal>
<goal>testCompile</goal>
</goals>
</execution>
</executions>
</plugin>
和
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.3</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<transformers>
<transformer
implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>Engine</mainClass>
</transformer>
</transformers>
<filters>
<filter>
<artifact>*:*</artifact>
<excludes>
<exclude>META-INF/*.SF</exclude>
<exclude>META-INF/*.DSA</exclude>
<exclude>META-INF/*.RSA</exclude>
</excludes>
</filter>
</filters>
</configuration>
</execution>
</executions>
</plugin>
仍然有文件未找到異常,但我相信它們可以解決。
首先了解Maven標准目錄結構約定。 現在,您的主要項目源位於src/test/
而不是正確的src/main/
,因此它們被視為在單元測試中使用。 因此,它不會被包裝。
