IntelliJ IDEA plugin that adds a 'Builder' action to the Generate menu (Alt+Insert) which generates an inner builder class as described in the Effective Java book. Works with IntelliJ IDEA 2019 and later.
public class JavaBean {
private final String foo;
private String bar;
private int qux;
private Double x,y;
private JavaBean(Builder builder) {
foo = builder.foo;
bar = builder.bar;
qux = builder.qux;
x = builder.x;
y = builder.y;
}
public static Builder newJavaBean() {
return new Builder();
}
public static final class Builder {
private String foo;
private String bar;
private int qux;
private Double x;
private Double y;
private Builder() {
}
public Builder foo(String val) {
foo = val;
return this;
}
public Builder bar(String val) {
bar = val;
return this;
}
public Builder qux(int val) {
qux = val;
return this;
}
public Builder x(Double val) {
x = val;
return this;
}
public Builder y(Double val) {
y = val;
return this;
}
public JavaBean build() {
return new JavaBean(this);
}
}
}In IntelliJ IDEA 2019 or later, open Preferences... > Plugins, search for innerbuilder. It should show up in
the plugin list, click INSTALL.
Download the plugin jar innerbuilder.jar and select Install Plugin From Disk in IntelliJ's plugin preferences.
Use Shift+Alt+B or Alt+Insert and select Builder.... Choose the fields to be included and press OK. When generating a
builder when a builder already exists, the plugin will try to update it. It will add missing fields and builder methods, but
never remove any fields or methods.
