I setup an eclipse project in myeclipse for spring and I received the following error when trying to build the spring core project using Ant build:
Buildfile: C:\Projects\ProjectName\projectSpringCore\build.xml
compile:
[mkdir] Created dir: C:\Projects\ProjectName\projectSpringCore\build
[copy] Copying 20 files to C:\Projects\ProjectName\projectSpringCore\build
[javac] Compiling 17 source files to C:\Projects\ProjectName\projectSpringCore\build
BUILD FAILED
C:\Projects\ProjectName\projectSpringCore\build.xml:25: Error starting modern compiler
Total time: 285 milliseconds
After some searching

This can arise for different reasons – though generally these reasons are all related – the version of Java being used by the Ant compiler in IDE does not match that already and referred to in JAVA_HOME.
To solve this in Eclipse, Go to Run > External Tools > External Tools Configurations > JRE
Select Separate JRE and match that with the one selected as JAVA_HOME.
You can verify the selected Java is the same using the Installed JREs tab
