9 The Eclipse IDE is a popular development environment and it fully supports
10 development using the Yocto Project.
11 When you install and configure the Eclipse Yocto Project Plug-in into
12 the Eclipse IDE, you maximize your Yocto Project experience.
13 Installing and configuring the Plug-in results in an environment that
14 has extensions specifically designed to let you more easily develop software.
15 These extensions allow for cross-compilation, deployment, and execution of
16 your output into a QEMU emulation session.
17 You can also perform cross-debugging and profiling.
18 The environment also supports a suite of tools that allows you to perform
19 remote profiling, tracing, collection of power data, collection of
20 latency data, and collection of performance data.

49 It is recommended that you have the Indigo 3.7.2 version of the
50 Eclipse IDE installed on your development system.
51 If you don’t have this version, you can find it at
52 <ulink url='&ECLIPSE_MAIN_URL;'></ulink>.
53 From that site, choose the Eclipse Classic version particular to your development
54 host.
55 This version contains the Eclipse Platform, the Java Development
56 Tools (JDT), and the Plug-in Development Environment.

62 For example, the following commands unpack and install the Eclipse IDE

64 into a clean directory using the default name <filename>eclipse</filename>:

72 One issue exists that you need to be aware of regarding the Java
73 Virtual machine’s garbage collection (GC) process.
74 The GC process does not clean up the permanent generation
75 space (PermGen).
76 This space stores metadata descriptions of classes.
77 The default value is set too small and it could trigger an
78 out-of-memory error such as the following:
