有没有一种方法可以在一个maven项目中编译多个java源目录?
当前回答
你可以用build-helper添加一个新的源目录:
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<version>3.2.0</version>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>add-source</goal>
</goals>
<configuration>
<sources>
<source>src/main/generated</source>
</sources>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>

这对我很有效
<build>
<sourceDirectory>.</sourceDirectory>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<includes>
<include>src/main/java/**/*.java</include>
<include>src/main2/java/**/*.java</include>
</includes>
</configuration>
</plugin>
</plugins>
</build>

这适用于maven 3.5.4,现在Intellij Idea将此代码视为源代码:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.3</version>
<configuration>
<generatedSourcesDirectory>src/main/generated</generatedSourcesDirectory>
</configuration>
</plugin>
Used the build-helper-maven-plugin from the post - and update src/main/generated. And mvn clean compile works on my ../common/src/main/java, or on ../common, so kept the latter. Then yes, confirming that IntelliJ IDEA (ver 10.5.2) level of the compilation failed as David Phillips mentioned. The issue was that IDEA did not add another source root to the project. Adding it manually solved the issue. It's not nice as editing anything in the project should come from maven and not from direct editing of IDEA's project options. Yet I will be able to live with it until they support build-helper-maven-plugin directly such that it will auto add the sources.
然后需要另一种变通方法来实现这一工作。由于每次IDEA在pom更改后重新导入maven设置,我新添加的源代码都保留在模块上,但它失去了源文件夹的选择,并且毫无用处。所以对于IDEA -需要设置这些一次:
选择-项目设置/ Maven /导入/保留源代码和测试 重新导入文件夹。 添加-项目结构/项目设置/模块/{模块}/来源/添加内容根。
现在把这些文件夹保存在导入状态也不是世界上最好的做法……,但试一试。
为了让它在intelliJ中工作,你还可以通过这种方式将generatedSourcesDirectory添加到编译器插件:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.1</version>
<configuration>
<generatedSourcesDirectory>src/main/generated</generatedSourcesDirectory>
</configuration>
</plugin>
