前言
技術棧
Windows 10 Java/JDK 1.8.0_202 Maven 3.6.3 spark 2.4.6 scala 2.12 hadoop 2.6.0-cdh5.10.0
- 作業系統中並沒有安裝 scala,利用 pom.xml 中的外掛編譯 scala 程式碼
報錯現象
編譯命令
mvn -D maven.test.skip=true clean scala:compile compile package
報如下錯誤

解決辦法
給編譯外掛新增 jvm 引數
jvmArg
,新增後scala-maven-plugin
外掛完整配置如下<plugin> <groupId>net.alchim31.maven</groupId> <artifactId>scala-maven-plugin</artifactId> <version>3.4.6</version> <executions> <execution> <id>scala-compile-first</id> <phase>process-resources</phase> <goals> <goal>add-source</goal> <goal>compile</goal> </goals> </execution> </executions> <configuration> <jvmArgs> <!-- 指定 scala 編譯時棧大小 --> <jvmArg>-Xss4m</jvmArg> </jvmArgs> <scalaVersion>${scala.version}</scalaVersion> </configuration> </plugin>
scala-maven-plugin

-Xms 指定jvm堆的初始大小,預設為實體記憶體的1/64,最小為1M; 可以指定單位,比如k、m,若不指定,則預設為位元組。 -Xmx 指定jvm堆的最大值,預設為實體記憶體的1/4或者1G,最小為2M;單位與-Xms一致。 -Xss 設定單個執行緒棧的大小,一般預設為512k。
