四个字就是:内存溢出了,出现这个问题,首先我们第一印象是maven内存不够用了,于是修改maven的bat文件,修改它的内存,但是修改后没有效果。然后我们会继续修改intellij-idea的内存,但是都没有效果。
为什么呢?因为我们没有找对点,我们应该修改pom.xml文件中编译插件的内存设置,如下:
<project> [...] <build> [...] <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.1</version> <configuration> <fork>true</fork> <meminitial>512m</meminitial> <maxmem>1048m</maxmem> </configuration> </plugin> </plugins> [...] </build> [...] </project>
你需要根据你的实际情况修改maven-compiler-plugin的内存配置。
