Failed to execute goal Org.apache.maven.plugins:maven-javadoc-plugin:2.10.1:jar (Attach-javadocs) on

A new development environment was built for the project today, and for some reason, Eclipse reported the following error. Search on the internet for a long time Leng did not find the relevant solutions, but also some netizens gave a good suggestion such as view the Java environment variable configuration, rebuild the deployment of MAVEN, etc.
There was no solution, and then there was the occasional document about the Eclipse memory settings that felt likely to be associated. Try modifying the memory configuration of Eclipse, which solves the problem. (The end of this article has the answer)

The solution is to set the-XMX in the Eclipse.ini file under the Eclipse installation directory (I set 512M after the 1024M error).
As to why the above problem may be related to the memory of the system, because-XMX is associated with the JVM running the maximum amount of memory (the default is 1/4 of the system's physical memory). Put your own physical memory large point may also solve the above problems after all, 1024M is not big.
