Debugging jar file with source code attached in eclipse

Question

Please let me know how I can debug any jar file with source code attached in eclipse.

When I tried to debug it, implementation is completed as desired but control never reached the breakpoints.

Answer 1

• Right-click on the jar referenced in your project, select 'properties'
• From 'Java Source Attachment' click 'Workspace...' button
• Select the 'src' folder from the jar project in your workspace

or if you want to do more steps:

• Right-click on project, select 'properties'
• From 'Jave Build Path' select 'Libraries' tab
• Expand (click '+') the jar you want to link source to
• Click 'Source attachment' (it should be saying 'Source attachment: (None)')
• Press the 'Edit...' button
• Follow from the second point in the shorter steps above
