有没有一种方法可以在一个maven项目中编译多个java源目录?

在配置中，您可以使用<compileSourceRoots>。
oal: org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-cli)
[DEBUG] Style: Regular
[DEBUG] Configuration: <?xml version="1.0" encoding="UTF-8"?>
<configuration>
<basedir default-value="${basedir}"/>
<buildDirectory default-value="${project.build.directory}"/>
<compilePath default-value="${project.compileClasspathElements}"/>
<compileSourceRoots default-value="${project.compileSourceRoots}"/>
<compilerId default-value="javac">${maven.compiler.compilerId}</compilerId>
<compilerReuseStrategy default-value="${reuseCreated}">${maven.compiler.compilerReuseStrategy}</compilerReuseStrategy>
<compilerVersion>${maven.compiler.compilerVersion}</compilerVersion>
<debug default-value="true">${maven.compiler.debug}</debug>
<debuglevel>${maven.compiler.debuglevel}</debuglevel>
<encoding default-value="${project.build.sourceEncoding}">${encoding}</encoding>
<executable>${maven.compiler.executable}</executable>
<failOnError default-value="true">${maven.compiler.failOnError}</failOnError>
<failOnWarning default-value="false">${maven.compiler.failOnWarning}</failOnWarning>
<forceJavacCompilerUse default-value="false">${maven.compiler.forceJavacCompilerUse}</forceJavacCompilerUse>
<fork default-value="false">${maven.compiler.fork}</fork>
<generatedSourcesDirectory default-value="${project.build.directory}/generated-sources/annotations"/>
<maxmem>${maven.compiler.maxmem}</maxmem>
<meminitial>${maven.compiler.meminitial}</meminitial>
<mojoExecution default-value="${mojoExecution}"/>
<optimize default-value="false">${maven.compiler.optimize}</optimize>
<outputDirectory default-value="${project.build.outputDirectory}"/>
<parameters default-value="false">${maven.compiler.parameters}</parameters>
<project default-value="${project}"/>
<projectArtifact default-value="${project.artifact}"/>
<release>${maven.compiler.release}</release>
<session default-value="${session}"/>
<showDeprecation default-value="false">${maven.compiler.showDeprecation}</showDeprecation>
<showWarnings default-value="false">${maven.compiler.showWarnings}</showWarnings>
<skipMain>${maven.main.skip}</skipMain>
<skipMultiThreadWarning default-value="false">${maven.compiler.skipMultiThreadWarning}</skipMultiThreadWarning>
<source default-value="1.6">${maven.compiler.source}</source>
<staleMillis default-value="0">${lastModGranularityMs}</staleMillis>
<target default-value="1.6">${maven.compiler.target}</target>
<useIncrementalCompilation default-value="true">${maven.compiler.useIncrementalCompilation}</useIncrementalCompilation>
<verbose default-value="false">${maven.compiler.verbose}</verbose>
</configuration>
这些都是3.8.1版本的编译插件可用的所有配置。不同的版本有不同的配置，您可以通过在通用mvn命令后使用-X运行代码来找到这些配置。就像
mvn clean install -X
mvn compiler:compile -X
并搜索id或目标或插件名称 这可能对其他插件也有帮助。Eclipse、intelliJ可能不会显示所有配置作为建议。

通过定义资源标记，这也适用于maven。您可以为src文件夹命名任何您喜欢的名称。
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.java</include>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
</resource>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.java</include>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
</resource>
<resource>
<directory>src/main/generated</directory>
<includes>
<include>**/*.java</include>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
</resource>
</resources>
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>
